Sorry, I don't understand your point.  It seems to be
claiming that the preprocessor doesn't do arithmetic
(a claim that is obviously incorrect), but your earlier
comments suggest that you understand things well enough
not to be making claims like that.

Anyway, I don't think it matters.  We seem to be agreeing
that autoconf isn't needed here.
