If I could assume GCC, the problem wouldn't have existed.  There are a
couple of contributors (one of them I mentioned in my previous mail)
who still use MSVC.  For now, I don't want to drop MSVC support, which
is why I want to avoid any *.in.h files that require include_next on
Windows.  Of course, if using include_next will become a necessity
(e.g., when gnulib's strftime is imported to Emacs, as Paul promised),
and MSVC users won't be able to suggest something to replace it, then
we will have no choice but drop MSVC support.

I searched on the Internet and didn't find any MSVC equivalent of
include_next, but maybe I missed something.
