getopt.h getopt() decl broken for many targets

["Aaron W. LaFramboise" <aaron98wiridge9 at aaronwl dot com>]

Targets, such as Windows, that don't have getopt() will probably have
get the following error when compiling binutils.

gcc -DHAVE_CONFIG_H -I.

warning: function declaration isn't a prototype
make[4]: *** [strings.o] Error 1

This is due to this code:

#if !HAVE_DECL_GETOPT
#if defined (__GNU_LIBRARY__) || defined (HAVE_DECL_GETOPT)
/* Many other libraries have conflicting prototypes for getopt, with
   differences in the consts, in unistd.h.  To avoid compilation
   errors, only prototype getopt for the GNU C library.  */
extern int getopt (int argc, char *const *argv, const char *shortopts);
#else
#ifndef __cplusplus
extern int getopt ();
#endif /* __cplusplus */
#endif
#endif /* !HAVE_DECL_GETOPT */

Is the situation described in this comment still true?  Would it be
possible to turn this whitelist into a blacklist?
