This looks to be the same problem reported in bug #10436:
http://www.postgresql.org/message-id/flat/20140524154250.1403.92643@wrigleys.postgresql.org

According to the mingw bug referenced at the end of that thread, this has
been fixed in mingw.  Please see if you can update.  If you can't do so
right away, a workaround is to remove -Wl,--disable-auto-import as
discussed in that thread.
