Hi,

I have got this error also with Xen-4.6.1. Identical.

I made a complete update of the computer, latest everything, incl. 
glibc-2.23, and gcc 5.3.0, kernel 4.4.4. It didn't work. Wiped 
everything and went back to glibc-2.17, and gcc 4.8.2. It did not help. 
It still refuses to compile. Running config and make on gmp separately, 
no problem.
I finally built Xen with --disable-stubdom, which worked.

Seems that the problem not necessarily is in glibc, but elsewhere.

The machine is based on Slackware 14.1, I tried the bleeding edge 
(almost 14.2), but backed down to a standard 14.1 (which is well over 2 
years old). I'm using one of the latest kernels, 4.4.5, for dom0.
CPU AMD FX-6100, 16GB RAM, AMD 990FX Chipset, AMD Radeon HD6450 
(graphics pass through), file system LVM-based.
Best regards,

Peter
