I just looked at the current version of obstack.c in glibc.  It uses
`ENABLE_NLS':

/* Define the error handler.  */
# ifndef _
#  if (HAVE_LIBINTL_H && ENABLE_NLS) || defined _LIBC
#   include <libintl.h>
#   ifndef _
#    define _(Str) gettext (Str)
#   endif
#  else
#   define _(Str) (Str)
#  endif
# endif

Thus, I think we should undefine ENABLE_NLS rather than HAVE_LIBINTL_H
to disable NLS when building generator files.  However, configure for
libiberty needs to be modified to add an `--enable-nls' option.  Similar
patches should be done for getopt.c and regex.c which also may use
NLS.
