While Visual Studio 2010 may have stdint.h, older versions of Visual Studio
such as Visual Studio 2005, do not have stdint.h.

Here's a patch to import the md5 module from gnulib into Emacs.
I haven't committed this yet, as I would like to test it more,
but thought I'd give a heads-up.
For Windows, I expect the hand-generated makefiles will need to be
changed to compile lib/md5.c instead of src/md5.c, since the file was
moved.
The patch that I wrote is below. I'm attaching the full patch
(including automatically generated changes), as a compressed file.
Import crypto/md5 module from gnulib.
* Makefile.in (MAKEFILE_MODULES): Add crypto/md5.
* admin/notes/copyright: Remove src/md5.c and src/md5.h as
special cases.
* src/Makefile.in (base_obj): Remove md5.o, since this file
is in lib now.
* src/deps.mk (md5.o): Remove.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
Regenerate.
* lib/md5.c: Regenerate. This renames the file from src/md5.c,
and adds some porting improvements from gnulib.
* lib/md5.h: Regenerate, likwise; rename from src/md5.h.
* m4/md5.m4: New file, from gnulib.

Yes, it looks like that would be the only change needed.
Please post here a message when you commit these changes, so that the
Windows build could be fixed ASAP after that.
Thanks.

Here's an updated version of the proposed patch to have Emacs use
the gnulib md5 module.
This differs from the earlier md5 draft
<http://lists.gnu.org/archive/html/emacs-devel/2011-02/msg00783.html>,
in that it also imports the stdint module from gnulib. The stdint
module lets C code use <stdint.h> without worrying whether the
underlying system has <stdint.h>, and this simplifies the md5 module.
This patch complicates Emacs configuration a bit, but we expect that
Emacs will eventually need <stdint.h> anyway, for other reasons, so we
might as well address that now.
As I understand it, Visual Studio 2010 has <stdint.h>, and if that can
be assumed then the Windows port shouldn't have to worry about
configuring stdint.h. If it can't be assumed, the Windows port will
have to create a lib/stdint.h that is good enough for Emacs. For now,
all that's needed in this stdint.h is a definition "typedef int
uint32_t;" but a more-complete stdint.h will be needed eventually.
Another minor fix in this updated patch is that a stray dependency on
md5.h was removed from the fns.o rule in src/Makefile.in.
Here are the handwritten files in the patch. I have attached the
complete patch, including autogenerated files, compressed to save
space.
2011-02-19 Paul Eggert <eggert@cs.ucla.edu>
Import simpler crypto/md5 module from gnulib, plus stdint module.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
* src/config.in: Regenerate.
* lib/md5.c, lib/md5.h: Regenerate with simpler version, which
assumes C99-style <stdint.h>, supplied by the stdint module.
* lib/stdint.in.h, m4/longlong.m4, m4/stdint.m4: New files,
generated from gnulib.
* src/deps.mk (fns.o): Do not depend on md5.h, fixing a typo in
the earlier patch.

Yes, both MinGW and MSVC have stdint.h.

But what about the dependency of fns.o on lib/md5.h instead?

Yes, thanks, that should be added, like this:
* deps.mk (fns.o): Depend on ../lib/md5.h.
