This is not a problem if you recall that GNU `ld' is a one-pass
linker.  Try this command:

	 gcc ... -lc -lm

(replace "..." with the rest of the arguments you need to give GCC to
link your program).  This will cause GCC to pick whatever functions
it finds in libc.a first, and only those it doesn't from libm.a.

Work is under way to add them; volunteers are welcome to come on board
and help make that happen.

As DJ points out, one of us already did ;-)
