That is just a quick way to mark all class members dllexport/dllimport
instead of having to do so for each one individually.
[I probably shouldn't throw fuel on the fire, but...]
FYI, there is a new version of Cygwin binutils that makes the DLLIMPORT
cruft obsolete:
http://www.cygwin.com/ml/cygwin-announce/2001/msg00100.html
In particular, check out Paul Sokolovsky's 'auto-import' functionality.
Oh yeah, I just remembered b20.1. I guess that you can forget about the
above. :,)

Cygwin and Win32 should treat DLLIMPORT the same.

Oops, I'm a little behind in reading pgsql-patches... Or, has this been
discussed on pgsql-hackers?

You are correct. As of 7.1.2, libpq++ was not part of the Win32 build.
