+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".
+
+Some clients may need -fwritable-strings.  twm is said to need it.
+
+The ANSIfication fix:
