This looks like a snippet of an autoconf AC_CHECK_LIB (or
AC_CHECK_FUNCTION) test. Such tests don't work with 32-bit Win32 APIs
-- on either Cygwin or MinGW -- because they don't take stdcall into
account. You'll need to modify the test to work around that.
Also, if you're using Cygwin, do you *really* want to be using Win32
OpenGL and not X11?
