In theory we could now remove the __declspec(dllexport) case for
BUILDING_DLL, as it should now be redundant with the fixed .DEF generator.

Unfortunately it looks like there's not going to be any getting around
having something that can turn into __declspec(dllimport) in the headers
for compiling things that link to postgres.exe, though.
