There should be an assignment on file, although it is signed by my employer
Softing Industrial Automation GmbH on Oct 25 2012 and countersigned by
John Sullivan on Dec 17 2012
The work that is intended to be covered by this assignment is mine.

I am also the maintainer of the GNU Mempool package:
https://www.gnu.org/software/mempool/
so I should be known to gnu.org, but maybe something got lost.

Is this assignment sufficient for contributing to gdb?


Thanks
Bernd.
