1.1     ! root        1: Our setup:
        !             2: 
        !             3:        Sun 3/60 with cgfour
        !             4:        SunOS 4.0 (plus what Sun calls their "general hygiene" patch tape)
        !             5:        XV11R3 + MIT fixes 1 through 8 + "Purdue enhancements" + one local
        !             6:                "ANSIfication" fix (previously reported to MIT,
        !             7:                and attached below)
        !             8: 
        !             9: I installed gcc 1.34 (plus the expr.c fix) and also ran the "fixincludes"
        !            10: script.

        !            12: I built the X stuff with with the "CC" line in the "Sun.macros" file set to:
        !            13: 
        !            14:              CC = gcc -fcombine-regs -fstrength-reduce -finline-functions -fpcc-struct-return -DPURDUE -Dinline=INLINE -DNOSTDHDRS
        !            15: 
        !            16: where -fcombine-regs, -fstrength-reduce, and -finline-functions specify desired
        !            17: optimizations, -fpcc-struct-return makes things compatible with the dbm library,
        !            18: -DPURDUE buys the Purdue speedups, -Dinline=INLINE avoids a problem with a
        !            19: variable named "inline" in the X file "fonts/bdftosnf/fontutil.c", and
        !            20: -DNOSTDHDRS avoids a problem with multiple (and conflicting) typedef'ing of
        !            21: "size_t" in the gcc-provided STDDEF_H and Sun's "sys/types.h".
        !            22:
