It would fix NetBSD 5.0 vs. NetBSD 0.9, though, because those branches
are strictly ordered.

Yes.

Anyhow, I talked to sjg about this and the conclusion is that
MAKE_VERSION does need to get defined to something in all builds of
make, and it really ought to be maintained properly too.

For now the makefile should pass a fixed date stamp (may as well go
with 20090326) and at some future point we can move this out of the
makefile and create a version.h for it.

The version should be bumped when new language features are added,
akin to config(1)'s version.

Do you want to do this or should I?
