Oops, you _really_ shouldn't put that "single quote" there, ansi preprocessors
that follow the standard explicitly will whinge.

Okay, "UL" is now added as a valid type specifier for integers.
However specifing the type will make no difference as the integer
type for preprocessor expressions is supposed to be the largest
available integer however you express it.

I'm not even sure specifing a type is actually legal, but I think it's
covered by the phrase "identifier-nondigit" in the syntax table.

That is a bug in the new bcc.c that's been there since it first appeared,
(Errm, 0.16.2) ho hum nobody noticed before. (Including me!!!)

Okay fixed, and I'll be uploading a new version tomorrow with those
and a few other changes.
