Our setup:

	Sun 3/60 with cgfour
	SunOS 4.0 (plus what Sun calls their "general hygiene" patch tape)
	XV11R3 + MIT fixes 1 through 8 + "Purdue enhancements" + one local
		"ANSIfication" fix (previously reported to MIT,
		and attached below)

I installed gcc 1.34 (plus the expr.c fix) and also ran the "fixincludes"
script.

I built the X stuff with with the "CC" line in the "Sun.macros" file set to:

             CC = gcc -fcombine-regs -fstrength-reduce -finline-functions -fpcc-struct-return -DPURDUE -Dinline=INLINE -DNOSTDHDRS

where -fcombine-regs, -fstrength-reduce, and -finline-functions specify desired
optimizations, -fpcc-struct-return makes things compatible with the dbm library,
-DPURDUE buys the Purdue speedups, -Dinline=INLINE avoids a problem with a
variable named "inline" in the X file "fonts/bdftosnf/fontutil.c", and
-DNOSTDHDRS avoids a problem with multiple (and conflicting) typedef'ing of
"size_t" in the gcc-provided STDDEF_H and Sun's "sys/types.h".

The ANSIfication fix:
