Uh, no, because that's backwards: we'd need the __declspec(dllimport)
in the backend code.

The best thing probably is not to have the duplicate declarations on
platforms that don't need 'em.  Unfortunately, I seem to recall that
the current coding was arrived at to forestall link problems on weird
platforms that *had* these symbols declared and yet we needed externs
anyway.  We might have to do something as ugly as "#ifndef CYGWIN".
