I guess you mean charset.i.  Anyway, I will need your help with
finding out what exactly causes Studio 2003 to fail, as I don't have
that installed.  Please find out what part of the macro-expanded
source causes trouble and post it here.

Evidently, yes, because a couple of people who regularly build Emacs
with newer versions of MSVC didn't complain.

I now added SIZE_MAX to nt/inc/stdint.h.

Why is the data type important?

Because the former can be followed by a semi-colon in any context,
like in an if or a while, while the latter will cause compilation
errors.

Please tell the details about this, I don't think I understand
completely what was the problem.
