It looks like your GL headers are not in gcc's include file path.

According to the GCC 2.95 installation instructions for CygWin, GCC
only looks in it's own installation area and in /Cygnus/cygwin-b20/ by 
default.  If you've just re-installed cygwin, you may have lost where
your GL headers were added to the compiler search path on your
previous install.

I'm not sure how you specify it for cygwin (C_INCLUDE_PATH environment 
variable maybe?), but the path to your GL headers (i.e. the parent
directory of GL/*.h) needs to be added to the compilers include search 
path.
