It was the simplest path - on windows (and AIx) extension symbols need to be
explicitly exported. We did that by building the objects constituting
extension libraries, collecting the symbols, generating an export file with
all the symbols, which then is passed to the linker. It was a lot less work
to just add the necessary PGDLLEXPORT annotations than make that export file
generation work for extensions.

Yes, or at least the simplest path.

It is.
