getopt_long not found, even though it is present

[Gerald Pfeifer]

Assume we are on a system which does have /usr/local/include/getopt.h,
and support for getopt_long, but where getopt_long is _not_ in libc.

Our configure then diagnoses

  #define HAVE_GETOPT_H 1
  /* #undef HAVE_GETOPT_LONG */

which leads a compilation error for tools/wrc/wrc.c which includes
"wine/port.h" and <getopt.h>, for _both_ define struct option.


As far as I can see, the problem here is that in tools/wrc/wrc.c we
check for the presence of HAVE_GETOPT_H, while in wine/port.h we check
for HAVE_GETOPT_LONG.

The patch below is one way to fix this problem, another way would be to
move the #inclusion of <getopt.h> from individual files to wine/port.h.

Yet another option would be the hack autoconf to try linking libgnugetopt
when looking for getopt_long, but I don't know how to hack this into
configure.

How should we resolve this?

I noticed the following fix by Alexandre, which is much nicer than the
original hack of mine:

  revision 1.38
  date: 2003/04/20 02:56:14;  author: julliard;  state: Exp;  lines: +3 -0
  Check for struct option independently of the getopt_long check.

Thanks!
