I believe that the attached patch is the correct solution --  I apologize
for the gyrations.  With the attached patch, Cygwin libpq++ builds
cleanly again.  The root cause was that DLLIMPORT was defaulting to
__declspec(dllimport) since BUILDING_DLL was *not* defined when building
the libpq++ DLL.

Unfortunately, to test my patch requires changing the following makefile:

    src/interfaces/libpq++/examples/Makefile

and the #includes in all of the *.cc to build against the source tree
instead of the following hardcoded installation directory structure:

    /usr/local/pgsql

I was able to manually build

    src/interfaces/libpq++/examples/testlibpq0.exe

against my Cygwin libpq++ without errors.  However, I have not tried to
actually test testlibpq0.exe.

Is this sufficient?  Or, do you want me to clean up libpq++/examples too?
(Or, is it silly to even ask? :,))  Let me know how you want to proceed and
I will submit a patch to pgsql-patches.
