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 Möller, 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.
