OK. Well, I didn't quite like the submitted patch for a couple of
reasons. First, it only affected VC2010 builds, and you said these
weren't the only ones affected. And second it didn't really highlight
what was being done.

So here are two patches, one for HEAD/9.2 and one for earlier releases,
that do this in a different way that is more obvious, and for all
versions of VC.

Please test. I will also test these.
