[PATCH] Compile popt under Windows using gnulib

[Richard W.M. Jones]

This patch allows popt from CVS to be cross-compiled for Windows using
MinGW and Win32 API (not Cygwin).

It uses Gnulib to supply the missing functionality -- mainly glob(3)
and globfree(3).

Note that the patch isn't "complete".  As you can see from the
modification to autogen.sh you are expected to have a checkout of
gnulib itself in a directory adjacent to popt (../gnulib/).  That will
pull in the additional files from Gnulib.  A better explanation is
probably to read the Gnulib manual:

http://www.gnu.org/software/gnulib/manual/gnulib.html#Initial-import

All the Gnulib modules imported are LGPLv2+ (except for one which is
public domain).

If you have the MinGW cross-compiler installed, eg. from [1], then you
can compile popt for Windows by doing:

  PKG_CONFIG_PATH=/usr/i686-pc-mingw32/sys-root/mingw/lib/pkgconfig \
  ./autogen.sh \
    --host=i686-pc-mingw32 --prefix=/usr/i686-pc-mingw32/sys-root/mingw

  make -C lib fnmatch.h                   # BUG IN GNULIB?

  make

You'll get a DLL, and test{1,2,3}.exe which can be run under Wine (or
even on Windows :-).

For reference you can find our mingw32-popt RPM sources here:
