	I run GRASS under SCO (that's a PC386 UNIX) (using mostly SCO's 
	cc rather than gcc)
	and I've had a couple of spurious floating point exceptions
	in GRASS programs (like adding two FP numbers such as 17 and 21...).
	I've finally decided to catch and ignore that signal in these
	programs (e.g. Not a very nice thing to do, but I
	couldn't think of anything else.
	Since you're probably using similar hardware, maybe you have a 
	similar problem? But then, works fine over here...
