In the future, you should say what compiler you're using, what
machine, etc.  Fortunately this problem is so common that it isn't
necessary.

The problem is that TurboC doesn't link in the floating point lib
unless it thinks it is needed.  And basically TurboC thinks it will be
needed if it sees a floating point function being used.  So to force
TurboC to link in the floating point library, put the pointless line:

	(void) exp(1.0);

somewhere in your code.  That should do it.
