Those were merely our thoughts on how to do it, alas we haven't had
the time yet to get anything implemented. The old makefile for Windows
was written in .bat and that did the vsvars trick, hardcoded to look
at various VSnn combinations, in order of most recent to oldest.

I think these experiments might have been pre-scons, I'm not sure if
we've tried it seriously since then.

Yes, that should be sufficient. Batch files can have goto's which
constitute structure, but I can't remember if any of the vsvars files
I looked up had any goto's in them.
