Hi Franz,

That's strange, I just tried building libpng from stable and get this:

$ i686-pc-mingw32-pkg-config libpng --libs
-L/Users/tonyt/dev/mxe/usr/i686-pc-mingw32/lib -lpng15 -lz 

so it looks like it should link correctly. How are you calling pkg-config, or 
are you using $(PREFIX)/$(TARGET)/bin/libpng-config (which should be changed in 
the test program)?

I'm not too sure how useful these would be, 

`i686-pc-mingw32-pkg-config gl --libs` `i686-pc-mingw32-pkg-config glu --libs` 

is a very verbose way of saying -lopengl2 -lglu32. These are part of the w32api 
and will always be in the default search paths. It's more a matter that 
packages using these should specify them in their respective *.pc files.
