Hopefully Craig will comment on the data warnings in the C++ sources.

Previously it tested _WIN32 instead of HAVE_WINDOWS_H, but someone (was
it you?) had a problem with that in one or other mode of building, so I
changed it (as per discussion on this list). [This reminds me of my PhD
theses, where one equation had > changed to >= and back so many times,
at the whim of supervisors and examiners, that the buildup of Snopaque
was getting serious...]
I'm afraid I can only do what I'm advised to do on this one... Help!

Those could do with the insertion of some casts.

Those might as well get some casts too.
Neither of the pcretest groups of warnings is anything to worry about.
