Well After quite a gyrations a friend of mine and i finally managed to get GCC
up and going on our Unix-PC's. After confronting the __STDC__ problem with the
stock compiler and stage 1 problems with virtual memory exhausted using 
optimization we finally got a version of 1.34 running with shared libraries and
optimized!!! 
	Next step, we sat down to do a few comparisons between GCC and the stock
compiler. Much to our surprise we found that with most small to medium programs
GCC actually generated a larger binary than stock. Well then why the heck should
we use this compiler we wondered??? Well i found a reason.....

We compiled dry.c (dryhstone benchmark program) with full optimization and 
the shared library and we got some very interesting results!!!

AT&T 3.51a cc	974		1037
GCC 1.34	1332		1332


More speed comparisons to follow on moria, nethack, etc. (if we can figure out
a reasonable way to benchmark games!!!)
