New Revision: 195815
URL: http://svn.freebsd.org/changeset/base/195815
Log:
Output DWARF debug information for global 'using' declarations, instead
of just blowing up. A very similar change to this exists which is
GPLv3 licensed, this is my own change.
This problem was triggered by running the Boost regression tests.
