You're right.  I'd forgotten how hard it is to get useful information out of
BSD lint; I try to do most of my linting on my SysV machine.  Okay, having
trapped myself in the corner, I will now proceed to walk across the wet paint.

I retract most of this thread.  My original comments stand, suitably modified:
(a) lint can help diagnose the problem (provided you tell it about the
library; this is `-lm' in most versions of Unix)
(b) if you don't have lint or equivalent functionality via compiler options,
then your vendor only sold you half a C compiler.
