-dnl NOTE: Because of portability issues between different autoconf
-dnl versions the AC_HELP_STRING macro has been removed from FPTOOLS_HAVE_OPENGL.
-dnl Furthermore, caching has been completely rewritten.
+dnl Some notes about the heavily changed OpenGL test below:
+dnl * Caching has been completely rewritten, but is still no perfect yet.
+dnl * Version detection for GL and GLU has been added.
