I am currently trying to port the GNU C Compiler to the UNIX/PC (3b1)
to use in my RISC architecture research.  I have succeeded in getting
the VAX configuration to compile and run on a small test file.

However, when I use the 68000 configuration files, I get a compiler
error from the 3b1 C compiler (cc) saying:
 
line 587 compiler error: out of tree space; simplify expression

Now the line in question is very big.  I hesitate to try to simplify
it since the source for it is a series of defines within defines....

I would like to be able to get the 68000 version of the compiler to 
work as another example case to study in generating my own configuration
files.

Question:
   Is there any hidden switch or option within the compiler to increase
the size of the internal tables (or whatever) of the compiler so that
I can get this to compile?

Thanks,
Dr. Ed Hepler
