[Mingw-cross-env-list] pkg-config problems in stable-branch

[Schrober]

Hi,

I've tried MXE and I am absolutely astonished what a big help it is.

But I also had three small problems related to pkg-config on the stable branch 
(didn't test any other branch because I had not time to do it).

I've used libpng and had the problem that the .pc file missed the zlib 
dependency and therefore no program not also using zlib were able to link 
against it. This can be fixed by adding following line to it:
"Requires: zlib"

The other problems are actually more or less the same. MXE doesn't add .pc 
files for glu and gl. I've worked around it by adding them manually, but maybe 
they can be added to the part of MXE which provides libopengl32 and libglu32

cat > usr/i686-pc-mingw32/lib/pkgconfig/gl.pc << STOP
Name: gl
Version: 0
Description: OpenGL
Libs: -lopengl32
STOP
cat > usr/i686-pc-mingw32/lib/pkgconfig/glu.pc << STOP
Name: glu
Version: 0
Description: OpenGL
Libs: -lglu32
STOP
