My understanding of the current organization of cygwin's include files
is that header files specific to cygwin's runtime appear in /usr/include,
header files specific to mingw's runtime appear in /usr/include/mingw and
Microsoft Win32 APIs common to both occur in /usr/include/win32api.

OpenGL is such a Microsoft API and the appropriate headers should be
placed in /usr/include/w32api/GL.  The current opengl-1.1.0-3 places
the headers in /usr/include and therefore doesn't support "-mno-cygwin"
compiles, as reported by your postings in February.  Adding a symbolic
link from /usr/include/mingw/GL to /usr/include/GL in the next release
would solve the issue, but not in keeping with the current cygwin
philosophy.

Similarly, "-mno-win32" should hide these win32 API headers.
