b05e961602 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.

fedda9c678 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++.

e2a74d7247 Add isnan() and isinf() to the global namespace in libstdc++'s <cmath>.
The standard (n3242, section 17.6.1.1, paragraph 4) says that, because these are
declared as macros in the C specification (even though they are
implemented as functions in the C++ library) they should be in the global
namespace.

A surprising number of configure checks rely on this.  It was broken by recent
cleanups to math.h.

93c7e89712 Allow the unwind functions int libgcc_s to interact correctly with libthr.
_Unwind_ForcedUnwind in libgcc_s takes as one of it's parameters a stop
function to tell it when to stop unwinding. One of the stop function's
parameters is a _Unwind_Exception_Class. On most architectures this is an
int64_t, however on ARM EABI the gcc developers have made this a char array
with 8 items. While both of these take the same space they are passed into
the stop function differently, an int64_t is passed in in registers r2 and
r3, while the char[8] is passed in as a pointer to the first item in
register r2.

Because libthr expects the value to be an int64_t we would get incorrect
results when it passes a function that take an int64_t but libgcc passes in
a pointer to a char array including crashing.

The fix is to update libgcc_s to make it pass an int64_t to the stop
function and to libstdc++ as it expects _Unwind_Exception_Class to be an
array.

a45e9cc023 Revert ABI breakage in libsupc++.
Unfortunately, the ABI was broken upstream for the 4.2 release, which we
imported.  We then shipped the broken version for several years and certain
ports (e.g. libobjc2) depend on it, so we're stuck with it for now...

We should revisit this for 10.0, since we're allowed to break the ABI then, but
until then we should keep the ABI we shipped with 8.x and 9.x.

2c4ebe03a0 Make it possible to use the debug versions of std::map and std::multimap
with clang, by removing two unneeded using declarations.  Otherwise, you
would get errors similar to:

/usr/include/c++/4.2/debug/map.h:77:20: error: dependent using declaration resolved to type without 'typename'
      using _Base::value_compare;
                   ^

N.B.: Take care when you actually use the debug versions of any
libstdc++ header.  They are more likely to contain problems, because
they are exercised far less often, and since the standard library
complexity guarantees don't always apply anymore, compile times can
drastically increase.

1fdc87e76d Some fixes so we can build libstdc++ with clang:
o Make the value_type, vector_type, iterator, __mutex_type types of
free_list class so we can access them
o In some cases template keywords must be inserted to treat classes as
dependent template names
o Remove two 'inline' keywords where they do not make sense
