The 1.2.x release series was retired about 6 months ago, and 1.2.8 is
far from being the latest version even in that retired release series
(it's more than 6 years old).

For a stable release, please use 1.4.x.  In particular, there are quite
a lot of recent changes on the RELEASE/1.4 branch (after 1.4.5) which
mean it can now be built with MSVC using the standard build system:

You can find bootstrapped snapshots from RELEASE/1.4 (equivalent to
release tarballs if we'd made a release at that point) here:

I didn't attempt 64-bit compilation, but would encourage people to try
to get that working.  As that message notes, you'll probably need to
disable (or fix) the remote backend for 64-bit compilation.

That's unlikely to be the right approach, especially as WIN32 is
apparently still defined for 64-bit compilations.

If you tell us what the error is, we might be able to help.  But please
try with a RELEASE/1.4 snapshot rather than 1.2.8.

No - currently the mail above is the nearest thing to docs on how to
build with MSVC at all.
