cpp on the s800 has a number of predefined symbols, including, but
not limited to hpux, unix, hp9000s800, and spectrum.  That is, cpp will
textually substitute '1' (for TRUE) for each of these predefines.

If a user program must use any predefined symbol in a context other
than conditional compilation (for example, using spectrum as an
identifier), he must compile his program with -Uspectrum, which has the
effect of removing spectrum from the table of predefines.

Note: for UX3.0, 'spectrum' will no longer be predefined; 'hppa' will
      take its place. This will be true for the XL1.2 C compiler too.
