You must have missed my postings on this in comp.windows.x:

Subject: Speedups for X11.2 Xsun
Summary: significant speedups, may work for other machines too

[...some introductory text deleted]

There are a few important things to do when compiling with gcc:
   [...some note about gcc 1.22 omitted]
   3) You need to compile server/os/4.2bsd/oscolor.c with the Sun-cc
   compiler, or else you need to recompile and link the dbm library
   into the server (remember to remove the "-ldbm" from the Makefile in
   the server directory, too).  The GNU compiler handles functions
   returning structures differently than pcc-based compilers, and
   "oscolor.c" uses the DBM "fetch" function to get items from a
   database.  The distinctive symptom of forgetting to do this on
   monochrome is that your xterm windows may be all black or all white,
   depending on normal preference, and color monitors will be straight
   B/W.

If you compile any of the clients, you may also need to use
"-fwriteable-strings" to get around some sloppy coding, notably in
xterm.  Within few weeks we may post a complete set of diffs for
compiling all the libraries and clients using all the gcc
optimizations.  Mostly these have required cleaning up some constant
placement and code ordering.  Compiling them with gcc doesn't make
a major difference, in most cases, however.

[...other notes on speedups omitted.]
