	This same bug is causing about 50-100 tests in the c-torture suite to fail to compile
	for a port I'm doing too!  This machine has 32 bit chars/ints/floats (it's only word addressed).
	And for a cross compiler hosted on Solaris 2.7, gcc gets an Arithmetic Exception at run time
	evaluating % 0.

	I suspect this may be a problem for several of the weirder target machines....
