Windows build of trunk

[Charles Day]

Adam Kessel has offered to test the register fixes for bugs 393383 & 426111
if we can come up with a Windows install .exe based on trunk.  Apparently he
is able to reproduce the problems repeatedly in 2.2.7 and it would be useful
to have him give trunk a test drive to see if he can break it. I kind of
recall that there may have been nightly Windows builds at some point, but
not any more. Would it be possible to make one on an ad hoc basis (i.e.
now)?

Cheers,
Charles
