Benjamin Kosnik f83295bafc re PR libstdc++/12658 (Thread safety problems in locale::global() and locale::locale())
2004-03-06  Benjamin Kosnik  <bkoz@redhat.com>

	PR libstdc++/12658
	* src/locale_init.cc (locale::locale): Lock critical regions with
	external mutexes.
	(locale::global): Same.
	* include/bits/concurrence.h (__glibcxx_mutex_define_initialized):
	Add in once bits for cases without __GTHREAD_MUTEX_INIT.
	(__glibcxx_mutex_lock): Same.

	* config/cpu/generic/atomicity.h: Remove
	_GLIBCXX_NEED_GENERIC_MUTEX, use concurrence.h.
	* src/misc-inst.cc: Move all locking bits out of this file.

	* config/os/hpux/os_defines.h: Remove _GLIBCXX_INST_ATOMICITY_LOCK.
	* src/misc-inst.cc: Same.
	* config/cpu/hppa/atomicity.h: Same.

	* config/linker-map.gnu: Remove types in the signature of atomic
	exports, as they may vary.

/* HP-UX, for reasons unknown choose to use a different name for
the string to [unsigned] long long conversion routines.
Furthermore, instead of having the prototypes in stdlib.h like
everyone else, they put them into a non-standard header
<inttypes.h>. Ugh.
<inttypes.h> defines a variety of things, some of which we
probably do not want. So we don't want to include it here.
Luckily we can just declare strtoll and strtoull with the
__asm extension which effectively renames calls at the
source level without namespace pollution.
Also note that the compiler defines _INCLUDE_LONGLONG for C++
unconditionally, which makes intmax_t and uintmax_t long long
types.
We also force _GLIBCXX_USE_LONG_LONG here so that we don't have
to bastardize configure to deal with this sillyness. */
