they are no longer on the central repository, but are on GBorg ... I've
made the appropriate chagnes to configure and Makefiles to reflect the
fact that libpq++ is no longer part of the central distribution, *but* I
used 'cvs remove' to remove the files themselves, so that the old branches
(ie. if we do a v7.2.2, we need it) still have access to the code ...
let me know if there are any problems ...
