The error seems to be this:
/home/seurer/gcc/git/gcc-test/libstdc++-v3/testsuite/22_locale/time_get/get=
_time/wchar_t/2.cc:62:
void test02(): Assertion 'errorstate =3D=3D ios_base::eofbit' failed.

This is a powerpc64 big endian system and it fails for both 32 and 64 bit r=
uns.
 This update works fine on powerpc64 little endian.
