Hmm.  What does it mean to attach a DLLIMPORT label to a class, anyway?
Is it meaningful to do so on Cygwin (as opposed to bare WIN32)?

No, but libpq's CVS tip is busted on WIN32.  See ongoing discussions
about fixing errno and strerror() handling on WIN32.  One way or another
we'll have it fixed soon.

BTW, I have no idea whether libpq++ (as opposed to libpq) has ever built
on WIN32 in the past.  The changes you are mentioning seem to be a
recent attempt to make it do so, which evidently needs further thought.
