Hi,  My understanding is that ARM now has appropriate assignments in
place to contribute to GLIBC.  Could someone with visibility of the
appropriate assignments file/database  confirm this ?


Yes:

GLIBC   Arm Limited     2013-12-23
Assigns Past and Future changes


Thanks for checking.

Note that longlong.h is shared with GCC and the two copies should be
updated in sync with each other if possible.


Understood.

This change looks OK to me, but I think it should wait until after the
2.19 freeze.


2.19 has been released; can anyone please help me commit the patch?

The original patch was posted here:

Thanks,
