grep-2.5 prototype problem on NetBSD-1.6M/alpha

[Thomas Klausner]

Hi!

cc -O2   -Werror -mieee  -DLOCALEDIR=\"/usr/share/locale\" -DHAVE_CONFIG_H

-c /nbsd/src/gnu/dist/grep/lib/hard-locale.c
cc1: warnings being treated as errors
/nbsd/src/gnu/dist/grep/lib/hard-locale.c: In function `hard_locale':
/nbsd/src/gnu/dist/grep/lib/hard-locale.c:69: warning: type mismatch in 
implicit declaration for built-in function `alloca'

The alloca test in regex.c works fine though.

For comparison, the one from hard-locale.c:
#ifndef __GNUC__
# ifdef HAVE_ALLOCA_H
#  include <alloca.h>
# else
#  ifdef _AIX
 #  pragma alloca
#  else
#   ifdef _WIN32
#    include <malloc.h>
#    include <io.h>
#   else
#    ifndef alloca
char *alloca ();
#    endif
#   endif
#  endif
# endif
#endif


The one from regex.c:
# ifndef alloca

/* Make alloca work the best possible way.  */
#  ifdef __GNUC__
#   define alloca __builtin_alloca
#  else /* not __GNUC__ */
#   if HAVE_ALLOCA_H
#    include <alloca.h>
#   endif /* HAVE_ALLOCA_H */
#  endif /* not __GNUC__ */

# endif /* not alloca */

The compiler is gcc-2.95.3, in case it matters.
I suggest finding a merged version that works on all supported systems.

On NetBSD, the alloca() prototype is in stdlib.h, btw.

Cheers,
 Thomas
