The GL now uses it's own internal sin and cosine routines thus eliminating
the need to link with -lm unless your program GL program specifically calls
sin(), cos(), or any of the routines provided by the math library.

I'm not sure in which release this because true though I know it is true
in at least 3.1G.  A way to check is to just link your application without
-lm.

WARNING: The GL internal sin and cosine routines are not for public 
consumption so you should not use them in your own applications.  Use of
GL internal routines in your application will almost certainly guarantee
binary IN-compatibility, shared-library or not.  Only GL public routines
are exported via the shared-library interface.
