Sorry rurban, this patch will break on my cygwin installation. I think
the problem is caused by more than an assumption that "mingw eq cygwin".
The real problem is that Cygwin hosts three flavours of library for
OpenGL: mingw, cygwin/w32api, cygwin/X11.
All your patch does is switch from Cygwin/w32api to Cygwin/X11.
Please see rt#56628 for more details.
Ah thanks. I missed your recent common on this.

The problem I had with the w32api libs was -lglut32. with linking
directly to the dll /usr/bin/glut32.dll everything works fine, and I'll
get rid of freeglut as default.
Now I only have to find out whatÄs wrong with that importlib, then I
send the revised patch. for now it is:
