I can push this patch for you, but you now also meet the requirements
for write access to the GDB repository (FSF assignment + 1 good patch).
If you are planning on contributing more patches, I suggest we get you
write access and let you commit yourself. WDYT? If not interested, just
let me know and I will push the patch.  Otherwise, can you contact me
in private for further instructions on how to achieve that?

Thanks,
