[Bug c++/42748] warnings about 'mangling of 'va_list' has changed in GCC 4.4' not suppressed in sytem headers

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

------- Comment #12 from doko at ubuntu dot com  2010-01-29 08:37 -------
checked the patch on the 4.4 branch; the error message for the test case in the
original report is gone, but there are some warnings about the mangling in the
libstdc++ files as well. not reopening yet, as I didn't check a build on the
trunk yet.
