Many of the winning entries of the International Obfuscated C Coding
Contest rely on older preprocessors.  Including this one, IIRC.
I remember that I had to use '-traditional' when compiling the entry
that calculated pi by computing the area of its source code.  You might
try -traditional or just -traditional-cpp.

It /is/ possible to eventually build this using gcc, though.  It's one
of the few IOCCC entries I've kept.  I think I was also using 2.8 then.
