It turns out that %h is marked in the source code as a POSIX.2
extension, along with quite a few other format specifiers (which are
also not supported on Windows).

Rather than putting a note in PROBLEMS specific to %h on Windows, it
might be better to modify the doc-string for format-time-string, to
make it clear which specifiers are guaranteed to work, and which are
POSIX.2 or GNU extensions, and will only work on plaforms that
support them.

Alternatively, we could introduce more conditional blocks to
strftime.c to do something sensible with the POSIX.2 extensions on
platforms that only support POSIX.1 formats.  I think most of them
could be handled without too much effort.
