C++ compiler problems with FC2

[Steve Friedman]

I've had a strange problem when trying to compile a C++ program.

On FC2, when using the standard C++ compiler (gcc 3.3.3), the first line 
of the program (#include <iostream>) caused a raft of errors regarding the 
file cmath.  I was then pointed to try gcc 2.96, but this didn't work for 
other reasons.

However, on FC1 (with gcc3.3.1), the program compiled cleanly (and ran on 
FC2).

What gives?
