* gthr-posix.h (__gthread_objc_init_thread_system): If
pthread_key_create fails, it's not clear what the return value is.
This obvious fix makes sure it always returns -1 if a problem
occurs.

* doc/gcc.texi: Use @defcodeindex for the index of options. Add
more index entries. Use more logical markup where appropriate.
Use TeX quotes and dashes.

* include/std/*: Add copyright notice.
* include/c_std/bits/*: Use using statements instead of extern "C".
* include/c_std/bits/std_cmath.h: Don't overload double versions
of math functions with __buitin versions, use global version to
prevent ambiguities. Remove define hacks.
* include/c_std/bits/std_cwchar.h: Using declarations for "C"
functions that have changed signatures and std::
declarations. Remove define hacks.
* include/c_std/bits/std_cwchar.h: Same, plus remove ambiguous
__builtins in std::. Remove define hacks.

* THREADS: Explain that when we compile libobjc inside GCC, we
always use thr-objc.c as a backend, which uses GCC's thread code.
From-SVN: r43058
* c-decl.c (grokdeclarator): Make the TREE_TYPE for declarations
accurately reflect its cv-qualification.
* c-typeck.c (type_lists_compatible_p): Ignore the top-levl
cv-qualifiers on function types.

* init.c (__objc_send_message_in_list): When setting a new entry
in __objc_load_methods use the method IMP as key, but check to see
if the method is in the hashtable by looking at the IMP also.
Also ... call the method after adding it to the hashtable rather
than before ... thus preventing an obscure possibility of infinite
recursion if a +load method itself loads a subclass.

* function.c (diddle_return_value): Kill code to determine
return value before expand_function_end.
(expand_function_end): Delay call to clobber_return_register
after fucntion return value is computed.
Re-install temporary reverted patch:
* toplev.c (rest_of_compilation): Call split_all_insns
before reg-stack and shorten-branches. Do shorten-branches
after reg-stack.
* final.c (shorten_branches): Remove insn splitting code.
From-SVN: r43044
* doc/gcc.texi, doc/invoke.texi: Add index of command line
options. Use @opindex to index them rather than other indexing
commands. Use @var{...} instead of <...>. Avoid spaces in names
inside @var. Don't use @kindex to index escape sequences in
source code.

* libsupc++/eh_alloc.cc: Ensure that required macros are
defined before including gthr.h. Ensure that we get the
version of gthr.h for which we know how to provide a
configuration.
* libsupc++/eh_globals.cc: Likewise. And, bring the threading
code path into line with the current EH model. Use std, where
appropriate.
