Another memo tells how to build clisp using Apple's own C compiler, a 
modification of the GNU C compiler.  If you read its "man" pages, there 
is mention of another compiler invoked as c++.  Using it, I tried 
building clisp various ways, but never successfully.  I could sometimes 
get through the "make" phase, I could never make it through "make 
check."  No cigar.

I was able build clisp using an unmodified GNU C compiler.  I had it 
installed coincidentally, because of GNU Pascal, or gpc.  Because of 
problems building gpc, the developer set up a two-phase build, where an 
unreconstructed GNU C is built and then used to build Pascal.  When you 
are through, you still have regular GNU C, but it is called gpcgcc to 
distinguish it from Apple's compiler.  I presume you can download alone 
it if you want it.

To compile clisp with gpcgcc I changed the CC environment variable:

   setenv CC "gpcgcc"

I then built clisp again, but without inserting the -traditional-cpp 
flag in the Makefile.  Interestingly, if you put the flag in, you crash 
out of the "make" phase.  I still needed a gigantic stack of 16384K.

Either way, with either compiler, you have to make two hacks.  In my 
humble opinion, it would be nice if Apple found some way to toggle that 
flag the other way around for consistency with GNU.
