(I've always considered it odd that some C system requires -lm, when
they don't require -lstdio. Both <math.h> and <stdio.h> are part of
of the C standard!)

Instead of dragging Autoconf into this mess, I just supply -lm
unconditionally. That should not harm.
Let me know if you find further problem with this.
