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.
                     11: 
                     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: 
1.1.1.2 ! root       16: where -fcombine-regs, -fstrength-reduce, and -finline-functions
        !            17: specify desired optimizations, -fpcc-struct-return makes things
        !            18: compatible with the dbm library, -DPURDUE buys the Purdue speedups,
        !            19: -Dinline=INLINE avoids a problem with a variable named "inline" in the
        !            20: X file "fonts/bdftosnf/fontutil.c", and -DNOSTDHDRS avoids a problem
        !            21: with multiple (and conflicting) typedef'ing of "size_t" in the
        !            22: gcc-provided STDDEF_H and Sun's "sys/types.h".
        !            23: 
        !            24: Some clients may need -fwritable-strings.  twm is said to need it.
