Do you work with DJGPP 1.x?  If so, then signals aren't supported in that 
version (v2.0 does), so you have only 2 alternatives I know about:

	1) Make sure your code doesn't trigger FP exceptions.

	2) Make your program set the control word of 80x87 so that the 
exceptions are ignored.  The DJ's ftp server, ftp.delorie.com, has a 
small program which shows how to fiddle with the control word, get the 
file /pub/djgpp/contrib/ctrl87.zip (this is mentioned in the FAQ list, 
btw).
