I just managed to make the import library and compile some code which uses wgl
but I still have some problems:

When I try to compile with -mwindows I get:
---------
/usr/bin/ld: warning: cannot find entry symbol _WinMainCRTStartup; defaulting
to 00401000
---------

Compiling with -mno-cygwin gives following errors:
---------
In file included from wgl.c:6:
/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2-5/../../../../include/GL/gl.h:44:
warning: `APIENTRY' redefined
/usr/include/w32api/windef.h:85: warning: this is the location of the previous
definition
---------
and lots of something like this:
---------
/cygdrive/c/WINDOWS/TEMP/ccRyOrHc.o(.text+0x495):wgl.c: undefined reference to
`glViewport'
/cygdrive/c/WINDOWS/TEMP/ccRyOrHc.o(.text+0x4b7):wgl.c: undefined reference to
`glMatrixMode'
/cygdrive/c/WINDOWS/TEMP/ccRyOrHc.o(.text+0x4bf):wgl.c: undefined reference to
`glLoadIdentity'
/cygdrive/c/WINDOWS/TEMP/ccRyOrHc.o(.text+0x4f1):wgl.c: undefined reference to
`gluPerspective'
---------

Without these switches everything works fine.
