I'm not aware of any change in -6 which could have caused that.
It appears the change that exposed the bug was the installation of
eglibc 2.17-7.
The stdc-predef.h header is now included automatically. It includes
<bits/predefs.h>.
The hppa64 header search starts from /usr/hppa64-linux-gnu/include
which is
linked to /usr/include. There isn't multiarch support so the compiler
doesn't find
bits/predefs.h in /usr/include/hppa-linux-gnu.
There is no glibc port for hppa64 linux.
I think the problem was introduced by the following change to gcc:
2012-10-23 Joseph Myers <joseph@codesourcery.com>
* config.gcc (*-*-linux* | frv-*-*linux* | *-*-kfreebsd*-gnu |
*-*-knetbsd*-gnu | *-*-gnu* | *-*-kopensolaris*-gnu): Use
glibc-c.o in c_target_objs and cxx_target_objs. Use t-glibc in
tmake_file. Set target_has_targetcm.
(tilegx-*-linux*, tilepro-*-linux*): Append to c_target_objs
and
cxx_target_objs rather than overriding previous value.
* config/glibc-c.c, config/t-glibc: New.
* doc/tm.texi.in (TARGET_C_PREINCLUDE): New @hook.
* doc/tm.texi: Regenerate.
* hooks.c (hook_constcharptr_void_null): New.
* hooks.h (hook_constcharptr_void_null): Declare.
It may be possible to disable this in config.gcc.
