Thanks. The first two warnings I mentioned are fixed.

Nope -- and I think that's because we only actually use stdbool.h
instead of our own macros if we think sizeof(bool) is exactly 1. But
we don't because pg_config.h.win32 says:
#define SIZEOF_BOOL 0
Perhaps that's what Peter E meant when he said "Windows could use some
manual adjustments in pg_config.h.win32 if anyone
cares"[1]. Should we just change this to 1? I'm going to go and test
that now. From googling sizeof(bool) am aware that ancient VC (before
5.0 more than 20 years ago) had a header that defined bool as int, but
that seems irrelevant now, right?
