Cool.  Send them to me and I'll move them into the tree.

R is a totally awesome statistical and graphics packaging.  It means they are dropping support for freeBSD because we don't have these functions.  That totally sucks, and to prevent that, I'd be willing to commit the #define nonsense.  Unless somebody has something better they could forward me for integration...
