End of GCC 4.6 Stage 1: October 27, 2010

[Jonathan Wakely]

Most of the failing libstdc++ tests which shouldn't be
platform-dependent fail with this message:
sh: /usr/bin/stty: Bad address

libstdc++-v3/config/os/mingw32/error_constants.h is missing several
entries, causing failures in the 19_diagnostics tests.

There are a few failures in 23_containers/vector/ext_pointer which
might be caused by an inttype definition on the platform, I'm not
sure.  A bugzilla PR should probably be opened if there isn't one
already.
