Good point.  It could presumably be forced to be built on such systems
for the maintainers of it, though, right?

Should this copy of libintl generally be updated to use existing
portability machinery in GCC?  There is a lot of stuff that the rest of
GCC knows how to get right that is reimplemented (or worse, missed) in
libintl.    Elsewhere in GCC we've eliminted code like this:

#ifdef __GNUC__
# define alloca __builtin_alloca
# define HAVE_ALLOCA 1
#else
# if defined HAVE_ALLOCA_H || defined _LIBC
#  include <alloca.h>
# else
#  ifdef _AIX
 #pragma alloca
#  else
#   ifndef alloca
char *alloca ();
#   endif
#  endif
# endif
#endif

#include <errno.h>
#ifndef errno
extern int errno;
#endif

Should we do the same for this version of libintl?

I can help with the process if we decide to do so.
