I'm trying to compile some very long (16 X ~500 terms) equations for numerical
work. When I try to compile this using the NeXT version of gcc (1.36) WITH 
optimization I get:
 
	"Internal compiler error.  Program cc1 got fatal signal 11."

Same (?) thing happens using Sun C 1.1:

	"compiler error: out of tree space; try simplifying"

The code DOES compile WITHOUT optimization under NeXT's gcc. It also compiles
WITH optimization under gcc 2.0 on a Sparc 1+ (it takes eons) and under "c89" 
on an R6000 (it takes considerably less than eons).

My question is: Is there a way to get around this problem (like some switch),
or must I get a newer compiler on the NeXTs (and throw out Sun C 1.1 on the
Sparcs :)?
