2011-11-30  Benjamin Kosnik  <bkoz@redhat.com>

        * acinclude.m4 (GLIBCXX_ENABLE_ATOMIC_BUILTINS): Remove
        size-specific macros. _GLIBCXX_ATOMIC_BUILTINS_1,
        _GLIBCXX_ATOMIC_BUILTINS_2, _GLIBCXX_ATOMIC_BUILTINS_4,
        _GLIBCXX_ATOMIC_BUILTINS_8. Use _GLIBCXX_ATOMIC_BUILTINS to
        indicate use of C++11 atomic builtins.
        * config.h.in: Regenerate.
        * configure: Regenerate.
        * include/Makefile.am (bits_sup_headers): Add atomic_lockfree_defines.h.
        * include/Makefile.in: Regenerate.
        * libsupc++/Makefile.am: Compile C++11 support with -std=gnu++0x.
        * libsupc++/Makefile.in: Regenerate.

        * include/bits/atomic_base.h: Move lock-free property macros...
        * libsupc++/atomic_lockfree_defines.h: ...here.
        * include/std/future: Use C++11 macros.
        * libsupc++/eh_ptr.cc: Same.
        * libsupc++/eh_throw.cc: Same.
