- update config.guess, config.sub
- rename install.sh to install-sh
2005/12/08 (4.7e)

- add config.guess, config.sub (needed for cross-compiling, etc).
- add configure check for Intel compiler.
- modify filename comparison for lint-library to ignore leading "./".
2004/03/25 (4.7c)
- fix a couple of places where valgrind reported a sscanf's result was not
always initialized.
- modify behavior of "-X" option so it does not cause preprocessor lines to
be written to the output. Preprocessor lines are needed for lint-library
text, but are inconsistent with other uses of cproto (patch by Kenneth
Pronovici).
- add configure option "--enable-llib", which allows one to configure cproto
without support for lint-library "llib" files. Since the "-X" option shares
the include-file tracking, this option can also be enabled (or disabled)
(discussion with Kenneth Pronovici, Bob Van der Poel).
- require an ANSI C compiler for building.
- updated configure script, using autoconf 2.52 + patch, along with macros from
vile/lynx/etc.
2004/03/09 (4.7b)
- added new -X option to limit the levels of include-files from which an
extern can come (Debian #235824).
- added new -i option to support inline function prototypes (Debian #228801,
patch by Kenneth Pronovici).
2003/04/05 (4.7a)
- add definition of YYFLAG, to enable the error-reporting code with bison 1.875
- add definition of YYSTYPE, to allow this to build with recent (aka "broken")
versions of bison (Debian #166140, Lukas Geyer <lukas@debian.org>).
- add gcc-specific __builtin_va_arg keyword (Debian #175862, Kenneth Pronovici
<pronovic@debian.org>).
- modify syntax.c to change token after "#endif" to a comment, thereby avoiding
deprecation warning from gcc 3.2, which would cause "make check" to show
unexpected results.
- resync with version 4.7 at http://cproto.sourceforge.net/
2003/01/05
- add gcc-specific __builtin_va_list keyword.
2002/02/25 (4.6e)
- correct length allocated for filename in include_file(), which was not big
enough if the $CPROTO environment variable was corrupted. From report by
<Sweasel18@aol.com>, using sharefuzz:
http://www.atstake.com/research/tools/sharefuzz1.0.tar.gz
- update configure.in to generate config.h directly using autoconf patch from
http://invisible-island.net/autoconf/
- remove makefile rules that attempt to recreate the configure script. As
demonstrated in numerous packages, it always reflects poor design.
- remove makefile rules to make shar files (comp.sources.misc is long gone).
- stop using changequote(), workaround for bugs in autoconf 2.5x
2000/11/09 (4.7)
- Report source file and line number in error messages in gcc-style format.
2000/08/10 (4.6d)
- use newer versions of mkdirs.sh and install.sh
- regenerate configure script with autoconf 2.13
- restructure aclocal.m4
- modify Makefile.in to allow $(bindir) and $(mandir) to be altered
independently of $(prefix) and $(exec_prefix) (patch by Carsten Leonhardt
<leo@debian.org>).
2000/07/08 (4.6c)
- add a clause to handle "__extension__" before extern declarations.
(report by Bob van der Poel <bvdpoel@uniserve.com>)
1999/12/27 (4.6b)
- correct check for size of vec[] array in yaccExpected(), broken in 4.6a
changes.
(report by Wolfgang Wander)
1999/12/19
- add keywords "restrict", "_Bool", "_Complex", "_Imaginary" based on c9x
draft.
- add keywords "__restrict__" and "__restrict", for gcc.
(report by Wolfgang Wander <wwc@rentec.com>)
1999/12/14 (4.6a)
- change vec[] array in yaccExpected() to be dynamically allocated. It was a
fixed-size (10 entries) array before. Also fix problem reported by Wolfgang
Wander <wwc@rentec.com>, which is that if the array were empty, it was passed
to qsort() with a zero-size, causing a core dump.
- add to syntax.c & corresponding test-cases the typedef/identifier example.
1999/10/21
- allow identifiers to be the same as typedef names, handle this case:
typedef int badStyle;
void badFunc(int *badStyle) { }
(reported by Paul Haas <paulh@iware.com>)
1999/01/03
- add '__extension__' keyword
1998/01/21 (4.6)
- Since cproto is no longer being distributed on USENET in shar file format,
the patchlev.h and MANIFEST files have been removed.
The patchlevel number has been removed from the version number.
- Moved files out of the porting directory into separate platform specific
directories. The emx directory has files used to compile using EMX.
The os2 directory has files used to compile on OS/2 using Watcom C/C++.
The win32 directory has files to compile on Windows 95 and Windows NT
using Watcom C/C++.
- correct order of include-path to keep standard include (e.g., /usr/include)
at the end of the search list.
- modified lint-library include-stack recovery to work on OSF/1.
- supply default initializer for lint-library const data
- corrected reset of __attribute__((noreturn))
- added '__volatile', '__const__', '__inline' keywords to grammar to
accommodate gcc.
- modified configure script to add several development/debugging options (i.e.,
--with-trace, --with-dbmalloc, --with-dmalloc).
- modified ifdefs to avoid using predefined 'unix' (not defined on AIX or CLIX)
1996/04/15 (Patchlevel 5)
- corrected instance of fclose on a file pointer after pclose was done (found
with Electric Fence).
- corrected script make_bat.sh to prevent expansion of \n in argument-string.
- Modified handling of lint library option to allow generation of lint libraries
for ANSI compilers (set -a -l).
- corrected a missing 'void' in parameter list
- modified to allow compile/test with 'dmalloc' library in addition to
'dbmalloc'.
- corrected memory leak in yyerror.c, and allocation-size for cpp command.
- added keywords to work with gcc 2.7.0
- corrected unresolved references to flush_varargs() when OPT_LINTLIBRARY
is not defined
1995/08/24 (Patchlevel 4)
- Added -S option to only output static declarations.
- Fix: The configure script didn't replace @CFLAGS@, @CPPFLAGS@ and @LDFLAGS@
in the makefile generated from makefile.in.
- Fix: The -a option generated incorrect function definitions.
- update test-cases for the -f2 fix in patch 3.
- remove dependency on GNU-make from makefile.in
- corrected configuration script that tests whether yyerror can be extended
(had cached wrong flag, preventing some configurations from being
recognized).
- added calls for 'flush_varargs()' to correct situation in lint-library output
where VARARGS comments were not reset properly when a function
was skipped.
- improved the logic of 'strip_name()' (used to compute include-directives for
the lint-library option) so that it recognizes the conventional include
directory created by a GCC install.
1995/01/06 (Patchlevel 3)
- check for a special case in lint-library generation, i.e., prototype
arguments of the form "*()", which need more parentheses for SunOS's lint.
- modified configure.in, aclocal.m4, makefile.in to work with autoconf 2.1
(also added install.sh - note that "install-sh" is not an MS-DOS-compatible
filename).
- derive the program name from the argv[0] entry, in case it's installed
under a different name.
- Fix: The -f2 option generated incorrect prototypes for functions that
take a variable argument list.
- use 'sed' rather than 'flip' to apply trailing CR's to MS-DOS scripts.
1994/10/26 (Patchlevel 2)
- modified grammar to recognize C++ ref-variables (i.e., '&' as a prefix to
identifiers at the top lexical level). Lint libraries are formatted without
this '&', since lint doesn't grok C++. This corrects an error in cproto 4.0
which caused '&' characters to be suppressed altogether, e.g., when filtering
with the "-t" option.
- modified rules that generate MANIFEST to put auto-generated scripts there
also, if they've been created (e.g., cd testing; make scripts).
- modified makefile.in to have shar target for both GNU shar and Rick Salz's
cshar utility.
- use 'const' in yyerror.c, otherwise the error-reporting auto-configuration
does not work.
- don't use "#elif" preprocessor control; not all systems support it.
1994/10/25 (Patchlevel 1)
- Added testing scripts for MS-DOS and VMS.
- Added makefile for Borland C++ for OS/2.
- Fix: When the -a, -t or -b options were used, '&' characters were stripped
from the output files.
- Fix: The system.h file should define EXIT_SUCCESS and EXIT_FAILURE
regardless of the presence of <stdlib.h>.
1994/09/24 (Patchlevel 0, dickey)
- corrected two malloc-defects in lint library generation (one place where
generated parameter name was copied rather than allocated, and another memory
leak).
- corrected generation of lint library function body, to handle function
pointers.
- changed the implicit lint library function type from "" to "void", to avoid
special-cases in the function-body generation.
- added logic using 'NestedParams' to suppress prototype-arguments in lint
library function-pointer arguments.
- corrected lint-library function parameter derived from prototype "char [2]"
(parameter name wasn't supplied).
- added PRINTFLIKE and SCANFLIKE to the comments interpreted for the lint
library translation.
- modified "LINT_PREPRO" comment to pass-thru all comment text if no count is
given.
- added new comment keyword "LINT_SHADOWED" to generate "#undef symbol" before
each function template in lint libraries (useful for processing files that
define both macros and functions with the same names).
- interpret GCC's __attribute__ noreturn and format for lint-library text
(GCC 2.5.8 preprocessor passes these macros through, GCC 2.6 apparently does
not).
- treat carriage-return (^M) as whitespace where appropriate.
- added configuration-test to avoid conflict with prototype for 'popen()'
- added several function-pointer regression test-cases
Version 3
1994/08/31 (Patchlevel 9, dickey)
- use 'autoconf' to make a UNIX configure-script.
- recognize GCC extensions '__inline' and '__attribute__'
- added ifdef OPT_LINTLIBRARY to allow compiling without the lint library
code (saves about 4kb).
- corrected some logic that made incorrect commenting for options -c -f1
(e.g., "void (*Sigdisp(int sig, void (*func)(int sig)))(int sig)").
- corrected logic that macroizes (e.g., with P_) functions like 'Sigdisp'
(it wasn't doing anything about the trailing "(int sig)").
- corrected handling of K&R conversion of mixed-mode functions (K&R style
with prototypes in arguments) to avoid losing comments.
- modified logic for options -c -f2 so that cproto inserts a space before
the beginning of a comment when it immediately follows an '*'.
- enhanced error reporting with new module yyerror.c which (attempts to)
report the expected token type/name when a syntax error is encountered.
- modified the grammar.y file to try to recover from errors at the next
semicolon (as well as the next right curly bracket).
- modified to process lex/yacc files with gcc as C-preprocessor.
- Added option "-O" to force redirection of errors without shell operations
(useful for VAX/VMS and MS-DOS in particular).
- added "\s" as a synonym for space in the format options (-P, -F, -C)
- tested on Solaris with lex/yacc and flex 2.4.6 / bison 1.22
(SunOS explorer 5.3 Generic_101318-42 sun4m sparc; gcc 2.6.0)
- tested on SunOS 4.1.1 with lex/yacc and flex 2.4.6 / bison 1.22
(SunOS calvin 4.1.1 1 sun4c)
- tested on IRIX with lex/yacc
(IRIX dbs3 5.2 02282015 IP19 mips)
- tested on Linux 0.99.15 with lex/yacc and flex 2.4.6 / bison 1.22 / byacc 1.9
- tested on MS-DOS with flex 2.37 / byacc 1.9 (built with turboc.mak).
(Bison uses too much stack space).
- tested on VAX/VMS 6.1 with VAX-C 3.2 and flex 2.4.6 / bison 1.22.
- moved non-UNIX files into 'porting' subdirectory.
- added 'testing' subdirectory, for simple regression tests.
- tested for memory leaks with dbmalloc (on Linux).
1993/06/09 (Patchlevel 8, internal: dickey/cthuang)
- added files 'lintlibs.c' and 'strkey.c'
- Allow dollar signs in identifiers
- Defined FAIL, SUCCESS to use in 'exit()' calls (VMS is approximately the
reverse of UNIX).
- Added option "-o" to force redirection without shell operations (useful for
VAX/VMS in particular).
- Added options "-l" (lintlibrary format), "-T" (typedefs), "-x" (externs
in include-files).
- Added "-C" option to cpp-invocation (to support VARARGS-decoding for -l
option).
- Modified grammar.y so that if -T option is turned on, instances of untagged
struct, union or enum are shown with the contents of the curly braces.
- Modified lex.l so that it sets 'return_val' iff at least one return statement
within curly braces returns an expression. Use this to support -l option.
- Modified semantic.c (for -l option) to put tabs after short names for better
readability. Also (only -l option), put a blank line before function
definitions and typedefs.
- Corrected lex.l so that it recognizes preprocessor lines within curly braces.
- Modified 'gen_prototype()' to trim 'extern' and 'auto' keywords from the text
(so that 'extern' is emitted in this function only if the -e option is
specified). Do this to support -l option (and to correct normal usage, which
implies that -e option is needed to put an 'extern' before declaration).
- Corrected test in 'put_decl_spec()' by using 'strkey()' (which tests for a
name, not simply a substring).
- Modified semantic.c to use 'put_string()' and related procedures to simplify
pretty-printing of lint-library text (mainly to control blank lines). (See
'fmt_library()').
- linted some xmalloc calls using ALLOC macro.
1993/06/01 (Patchlevel 7, cthuang)
- Fix: The processing of string literals is now more robust.
- Removed the -f4 option which generated prototypes like
int main P_((int argc, char **argv));
Use the -m option now to put a guard macro around the prototype
parameter list. Use the -m option together with -f3 (which is the
default) to produce the same output as the old -f4 option. The option
to set the guard macro name is now -M.
- Comments in prototype parameter lists are now disabled by default.
Use the -c option now to output these comments.
- Can now process #include directives in which the file is specified with
a #define macro.
- Now does not convert function definitions that take the formal
parameter va_alist from <varargs.h>.
- Now recognizes the GNU C modifiers __const and __inline__.
Patchlevel 6
- Fix: A function in lex.l exploited the ANSI C feature of concatenating
string literals. This prevented the module from being compiled with
pre-ANSI C compilers.
Patchlevel 5
- Fix: The -v option did not output declarations for function pointers.
- Fix: String literals continued over more than one line messed up the
line number count.
- Fix: The program generated incorrect prototypes for functions that
take a variable argument list using <varargs.h>.
- Fix: When converting functions from the standard input, cproto
generated no output if no functions needed to be converted.
- Fix: Now does not output a warning if an untagged struct is found in a
typedef declaration.
- Added the -b option which rewrites function definition heads to
include both old style and new style declarations separated by a
conditional compilation directive. For example, the program can
generate
#ifdef ANSI_FUNC
int
main (int argc, char *argv[])
#else
int
main (argc, argv)
int argc;
char *argv[]
#endif
{
}
Added the -B option to set the preprocessor directive that appears at
the beginning of such definitions.
- Added the keyword "interrupt" to the set of type qualifiers when
compiled on a UNIX system.
- The MS-DOS version now recognizes the type modifiers introduced by
Microsoft C/C++ 7.00.
- Now recognizes ANSI C trigraphs (yuck!).
- Now use "#if __STDC__" instead of "#if defined(__STDC__)".
- GNU bison orders the y.tab.c sections differently than yacc, which
resulted in references to variables before they were declared. The
grammar specification was modified to also be compatible with bison.
Patchlevel 4
- Fix: A typedef name defined as a pointer to char, short or float was
incorrectly promoted if it was used to specify a formal parameter.
For example, for the definition
typedef char *caddr_t;
int strlen (s)
caddr_t s;
{
}
cproto generated the incorrect prototype
int strlen(int s);
- Added implementation of the ANSI function tmpfile() for systems that
don't have it.
- If compiled with Microsoft C, cproto preprocesses its input by running
the command "cl /E". To eliminate the error messages when the file
<malloc.h> is included, the program now recognizes the specifier
_based(void).
Patchlevel 3
- Fix: The program didn't generate prototypes for functions defined with
the extern specifier.
- Fix: The -c option didn't output a space before parameter names in
generated prototypes.
- Added the -E option to specify a particular C preprocessor to run or
to stop the program from running the C preprocessor.
- Added the -q option to stop the program from outputting error messages
when it cannot read the file specified in an #include directive.
- Made the yacc specification compatible with UNIX SYSVR4 yacc.
Patchlevel 2
- Fix: The function definition conversion may produce a mangled function
definition if an #include directive appears before the function and
no comments appear between the directive and the function.
- Fix: The size of the buffer allocated for the C preprocessor command
string did not include enough space for options set in the environment
variable CPROTO.
- Replaced the -n option with -c which disables all comments in the
generated prototypes.
- Replaced the enum's with #define constants to accommodate C compilers
that don't like enumerators in constant expressions.
Patchlevel 1
- Fix: The program was calling ftell() on an invalid FILE pointer.
Patchlevel 0
- Added options to convert function definitions between the old style
and ANSI C style.
- Options can be specified from the environment variable CPROTO.
- The MS-DOS version recognizes more Microsoft C and Borland C++ type
modifiers (such as _cdecl, _far, _near).
- Fix: Formal parameters specified with typedef names were not promoted.
For example, for the definition
typedef unsigned short ushort;
void test (x)
ushort x;
{
}
cproto generated the incorrect prototype
void test(ushort x);
while the correct one is
void test(int x);
- Fix: Incorrect prototypes were generated for functions that returned
function pointers. For example, cproto generated an incorrect
prototype for the function definition
void (*signal(int x, void (*func)(int y)))(int z)
{
}
- Fix: Changed calls to memory allocation functions to abort the program
if they fail.
Version 2
Patchlevel 3
- Made cproto compatible with GNU flex.
- After compiling with the preprocessor symbol TURBO_CPP defined, on
MS-DOS systems, cproto will pipe its input through the Turbo C
preprocessor.
- Fix: Typedef names may now be omitted from typedef declarations.
For example, every C compiler I tried accepts
typedef int;
and some even give warnings when encountering this statement.
Patchlevel 2
- Cproto is now able to generate prototypes for functions defined in lex
and yacc source files named on the command line. Lex and yacc source
files are recognized by the .l or .y extension.
- Fix: The memory allocated to the typedef symbol table was not being
freed after scanning each source file.
- Fix: Failure to reset a variable during error recovery caused
segmentation faults.
Patchlevel 1
- Fix: Cproto incorrectly generated the parameter "int ..." in
prototypes of functions taking variable parameters.
- Fix: Function definitions can now be followed by an optional
semicolon. I found this feature in every C compiler I tried.
Patchlevel 0
- Added formal parameter promotion.
- Added prototype style that surrounds prototypes with a guard macro.
- Handles C++ style comment //.
- Nifty new way to set prototype output format.
- Got rid of the shell wrapper used to pipe the input through the C
preprocessor (cpp).
- For the port to MS-DOS, I modified cproto to run without cpp, but
since I didn't want to reimplement cpp, the program processes only the
#include and #define directives and ignores all others. Macro names
defined by the #define directive are treated like typedef names if
they appear in declaration specifiers.
Version 1
Patchlevel 3
- Fix: identical typedef names and struct tags should be allowed.
For example:
typedef struct egg_salad egg_salad;
struct egg_salad {
int mayo;
};
void dine(egg_salad l)
{
}
Patchlevel 2
- Fix: A typedef statement should allow a list of typedefs to be declared.
Example:
typedef int a, *b;
- Fix: When run with the -v option on this input, cproto did not output
a declaration for variable "b":
char *a="one"; char *b="two";
- The options were renamed. Added new options that change the output
format of the prototypes.
Patchlevel 1
- Fix: Incorrect prototypes were produced for functions that take
function pointer parameters or return a function pointer. For example,
cproto produced an erroneous prototype for this function definition:
void
(*signal (sig, func))()
int sig;
void (*func)();
{
/* stuff */
}
- The lexical analyser now uses LEX. It should still be compatible with
FLEX.
