Yes, but it's also for Unix: PYLONG_BITS_IN_DIGIT is only set when the --
enable-big-digits option is supplied to configure. So the code in
pyport.h always gets used for a plain ./configure && make.

I agree with you to some extent, but I'd still prefer to leave the 15-bit
definitions as they are, partly out of a desire not to make unnecessary
changes. The 'unsigned short' type used for 15-bit digits is both
theoretically sufficient and not wasteful in practice.
Barring further objections, I'm planning to get the
30bit_longdigit20.patch in later this week.
