Yeah, I think if we can get rid of the evil date-based versioning, then
this could be done like

diff --git a/src/makefiles/Makefile.win32 b/src/makefiles/Makefile.win32
index 17d6819644..609156382f 100644

Probably needs some careful checking of the quoting. But that should be
the right thing in principle.
