Hi Sylvain,

In mingw-cross-env, freeglut 2.8.0 seems to build fine without any 
significant patches. The recipe is here:

http://hg.savannah.gnu.org/hgweb/mingw-cross-env/file/9f3e2e08c437/src/freeg...

We do apply a patch to add pkg-config support:

http://hg.savannah.gnu.org/hgweb/mingw-cross-env/file/9f3e2e08c437/src/freeg...

Sorry I confused myself.  I meant after 2.8.0, in the SVN version,
which is what my patch is based on.

If I sent you an e-mail, you can suspect that I already know about
mingw-cross-env (plus I used to be a Savannah admin) ;)

The pkg-config support sounds nice, are you willing to push it
upstream?

FYI: I just filed a proposal in their issue tracker:

I implemented pkg-config support a couple weeks ago:
http://freeglut.svn.sf.net/viewvc/freeglut/trunk/freeglut/freeglut/freeglut....
http://freeglut.svn.sf.net/viewvc/freeglut/trunk/freeglut/freeglut/CMakeList...

The build system is based on CMake now.  If you want to implement your
-DFREEGLUT_STATIC idea in CMake, I can include it in the repository.

But maybe we should go and complain to the pkg-config guys that a
Cflags.private field would be welcome in .pc files?  :)
