I think it's r201508, but in any case, I'm attaching a patch which fixes
this build error.  Only very lightly tested so far, with configure
--target=sparc-linux with build&host x86_64.  Was able to build a cc1
and step through the changed code in the debugger, though am getting
"cc1: error: no include path in which to search for stdc-predef.h"

Looks good, please install if not already done.
