+ * 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.
