I just discovered that there is a whole bunch of new routines in
the GL library (-lgl) with awful, short names like "v3f".

I seem to recall SGI *promising* that now that FLEXNAMES were
the default, all *new* routines for the GL library would have
a distinctive prefix on their names.  For example,

	"v3f"	should have been "gl_v3f"

and then the "C" extern namespace would not be all cluttered up.

This is a giant pain, with SGI library symbols clashing with
perfectly valid extern variables in my programs.
PLEASE STOP IT!
