They don't. PGXS isn't compatible with MSVC. We really should come up
with something that is, but that work hasn't been done. The point is
that the vast majority of the people who use windows don't care a bit
for building from source - which decreases the urgency of doing such a
thing.

Sorry for pehaps bringing up an already closed topic, but what happened
to previous discussions about using cmake? If you want examples, there
are now cmake buildfiles for pgAdmin3 (they're not the primary ones yet,
but they're there)
