Merge r133175 from upstream:

2008-03-13 Dennis Czeremin <dennis.czeremin@smiths-heimann.com>

PR libstdc++/35566
* include/bits/stl_multimap.h (multimap<>::multimap(_InputIterator,
_InputIterator)): Forward to _M_insert_equal, not _M_insert_unique.

This patch was GPL2 at the time and fixes a regression introduced with
the merge of GCC r129013 in FreeBSD r236829.

Revert r263694, and apply a better fix to squelch unnecessary warnings
from clang about possible keywords being treated as identifiers for the
remainder of the translation unit (a.k.a. -Wkeyword-compat), when using
libstdc++ in combination with -Wsystem-headers. This will not only fix
devd, but any C++ program using libstdc++.

Add explicit braces to avoid dangling else in stl_tree.h. This silences
the following warning produced by clang trunk:
