[Bug c++/42748] New: excess errors in testsuite runs (the mangling of 'va_list' has changed in GCC 4.4)

["doko at ubuntu dot com" <gcc-bugzilla at gcc dot gnu dot org>]

see http://gcc.gnu.org/ml/gcc-patches/2010-01/msg00670.html and followups. seen
on the gcc-4_4-branch and the trunk, glibc version is eglibc-2.11.1

when running the libstdc++v3 testsuite on arm-linux-gnueabi, a lot of test
cases fail with excess errors, e.g.

  FAIL: 17_intro/using_namespace_std_tr1_neg.cc (test for excess errors)

Excess errors:
