Update.
2003-08-22 Simon Josefsson <jas@extundo.com>
* argp/argp-fmtstream.h [!__attribute__]: Define to nothing.
* argp/argp-help.c: Don't include malloc.h, some platforms
complain and it doesn't appear to be used.
[!_LIBC && HAVE_STRERROR_R && !HAVE_DECL_STRERROR_R]: Declare
strerror_r.
[!_LIBC && !HAVE_STRERROR_R && !HAVE_DECL_STRERROR]: Declare
strerror.
(hol_entry_long_iterate): Change __attribute to __attribute__.
(_help, __argp_error, __argp_failure) [!_LIBC && (HAVE_FLOCKFILE
&& HAVE_FUNLOCKFILE)]: Protect call to flockfile and funlockfile.
(__argp_basename) [!_LIBC]: New. Taken from LSH, by Niels M�ller,
modifed after comments from Ulrich Drepper.
(__argp_short_program_name): Ditto.
(__argp_state_help, __argp_error, __argp_failure): Use it.
(__argp_failure): Use strerror when necessary.
* argp/argp-namefrob.h (__flockfile, __funlockfile, __mempcpy)
(__strchrnul, __strerror_r, __strndup) [!_LIBC]: Remove __-prefix.
(clearerr_unlocked, feof_unlocked, ferror_unlocked)
(fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked)
(fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked)
(putc_unlocked, putchar_unlocked) [!_LIBC && !HAVE_DECL_*]: Map to
non-unlocked functions.
[!_LIBC]: Add prototypes for __argp_basename and
__argp_short_program_name.
* argp/argp-parse.c (argp_default_parser): Only use
program_invocation{_short,}_name if declared.
(parser_init): Use __argp_short_program_name.
* argp/argp-xinl.c [_LIBC || HAVE_FEATURES_H]: Add CPP check for
'#include features.h'.
* argp/argp.h [!__attribute__]: Define to nothing.
