+	print '; trailing number is the number of bytes of '
+	print '; parameter data pushed onto the stack.  The'
+	print '; callee is responsible for popping this data'

+	print '; However, the Microsoft OPENGL32.DLL does not export'

+	print '; Were it not for this problem, this file would not'
+	print '; be needed (for the gl* functions) since the entry'
