OK, I made that change on the emacs-24 branch (revision 111035).
There should be a new pretest of Emacs 24.3 out of that branch soon,
and a precompiled Windows binary will follow.  Watch the announcements
on emacs-devel.

This change will be merged to the trunk soon, so the few people who
provide snapshots of the trunk will probably soon upload a binary with
this change.

When you do get hold of a new binary with the change, please run some
tests with files on the DFS, and please report any findings.

I will try to improve things in this respect (on the trunk).

The x64 version can for now be built only with MSVC.  MinGW64 is not
yet supported.  Volunteers are welcome.

Thanks.
