Floating point exceptions with bzflag

[Stephen Montgomery-Smith]

Dear Chuck,

I am really enjoying the games/bzflag port.  But every so often it 
crashes with a floating point exception.  My guess is that the other 
operating systems simply ignore them.

The following (band aid) patch seems to fix the problem:
