I'm really not concerned about that - a build rule to link with the
right library based on pointer size is trivial.

They have two separate installation directories for 32 and 64 bit
packages. With PostgreSQL though, we'll quite possibly be shipping
both 32 and 64 bit components in the same installer, and thus going
into the same installation directory. We may have no choice about
that, as we can't force all the dependent libraries to add 64 bit
support when we need it.
