[MinGW-dvlpr] getopt

[Danny S. <dan...@cl...>]

The NetBSD getopt which is in the the cygwin distro compiles and tests
okay (using the libiberty testcase) with the following simple
modifcation to getopt.c

*** getopt.c Wed Nov 07 11:47:23 2001
--- getopt.c.mingw Sun Mar 02 07:54:47 2003
***************

+ #ifndef __MINGW32__
  #include <sys/cdefs.h>
+ #else
+ #define __P(protos)     protos  /* full-blown ANSI C */
+ #endif

  /*#include "namespace.h"*/

There are  (IMO) obvious advantages to sharing code with cygwin.

I have not tested yet with gcc  or binutils builds, but if no problems
are there any objections to putting this  getopt into libmingwex.a and
the header getopt.h into mingw's include. The header may need to be
guarded with  #if defined __MINGW32__ && !defined __NO_ISOCEXT

The __P(protos) definition could instead  go into _mingw.h.
