That's preferable, although it might be better to create wrapper
functions than macros, e.g.:

	int G_math_somefunc(void) { return somefunc(); }

Excessive use of macros can be a nuisance; macros don't show up in
"nm" output, or in gdb backtraces, can't have breakpoints set on them,
can't be called from gdb, etc.
