It will, and no, I didn't.  Note that the interface is not fixed yet,
we did not merge it into master for a reason.

The patch id:1456616530-2230-1-git-send-email-jus...@gnupg.org will
take care of that as well.

I'm not talking about glibc or gcc of course.

This sounds like it could affect the implementation in Rump, which is partly
based on libddekit. Did you take this into account?

See the code in:

  
https://github.com/rumpkernel/pci-userspace/blob/master/src-gnu/pci_user-gnu.c#L169

and precompiled testcase in:

Thanks!
