If you can suggest a safe way of making these work for both VS 6 and
the later versions, we could consider installing the changes before
the release.  TIA

Thanks.  If nothing else, we should probably detect MSC_VER 1400 and
warn that it's unsupported.

I worked on that, and had quite a few more problems (related to the
changes in the system headers which come with VS 2005 and to the fact
that there's no single-threaded C library anymore).  I solved those,
but then hit a brick wall when emacs-bootstrap built but crashed
during dumping.  I don't have time to debug the crash, so unless
someone else figures out how to solve it, I guess we will just say
that VS 2005 is unsupported by Emacs 22.1.

I can post the patches I needed to get Emacs to compile with VS 2005,
if someone wants to work on this.

Btw, the bare-bones download of VS 2005 couldn't even begin compiling
the test programs during `configure', since there's no windows.h
header file.  I needed to force VS 2005 to use the Platform SDK
include directory, to get it to compile.  Maybe that's one reason
Emacs crashed, but then how to get the missing headers?
