Carl,
	You might want to try out the cpp from GCC 1.39.  The only
changes you'll have to make to the code involve adding the following
lines to cccp.c and cexp.c:

	#ifdef _IBMR2
	#pragma alloca
	#endif

Probably best to insert the lines just after the initial comments.
Typing 'make cpp' should create cpp (and cccp unless you change the
makefile).

Hope this helps
