Changes to the WRPRC configuration distribution for Release 2.04
31 August 1993

Dumped the testcf directory and moved the function of that Imakefile into
config/Imakefile.  You assess it with "make test" in the config directory.

Dumped PreProcessCmd/PREPROCESSCMD.  Appears to be vestigial.  (Only used
a single time in X11R5, and I've never used it in my projects.)  CppCmd/CPP
is a reasonable substitute.

Decoupled ALLINCLUDES from ALLDEFINES.  This necessitated a redefinition of
LINTFLAGS, CFLAGS, and DependTarget(), all of which reference ALLDEFINES.

Changed names of SimscrLib, DepSimscrLib, SeqnumLib, DepSeqnumLib to
SimScrLib, DepSimScrLib, SeqNumLib, DepSeqNumLib.

Added SpecialCObjectCompile() rule for specifying special compile flags
for compiling particular object files.

Most of the old tertiary.ms has been absorbed into reference.ms.  The
remainder was renamed limits.ms.

Renamed config/unsupported to config/untested.
