thanks Andre ! the fix worked. I can now compile helloglut and many of the red book opengl demos.
I noticed that glGetMinmax and some histogram related functions are not supported. It is possible that this is because these are opengl 1.2 functions. By setting appropriate flags I got the appropriate GL_flags set correctly: however it appears that the libopengl32.a supplied with cygwin is only opengl1.1 compliant, which appears to be consistent with the README. I have more recent nvidia drivers (I think :)): Is there any way to convert them to to a linkable form ? (i.e using dlltool or something like that).
