c_locale.h (__convert_from_v): Only switch to the "C" locale if the current one isn't already "C" (for old glibcs).

Browse source 
2007-05-24  Paolo Carlini  <pcarlini@suse.de>

	* config/locale/gnu/c_locale.h (__convert_from_v): Only switch to the
	"C" locale if the current one isn't already "C" (for old glibcs).
	* config/os/gnu-linux/ctype_noninline.h (ctype<char>::classic_table,
	ctype<char>::ctype(__c_locale, const mask*, bool, size_t),
	ctype<char>::ctype(const mask*, bool, size_t)): Likewise, for generic
	locale model.
	* config/locale/gnu/messages_members.h
	(messages<>::messages(__c_locale, const char*, size_t),
	messages_byname<_CharT>::messages_byname(const char*, size_t)):
	Only dynamically allocate memory if __s != "C".
	* config/locale/gnu/time_members.h
	(__timepunct<_CharT>::__timepunct(__c_locale, const char*, size_t)):
	Likewise.
	* config/locale/generic/time_members.h
	(__timepunct<_CharT>::__timepunct(__c_locale, const char*, size_t)):
	Likewise.

	* testsuite/util/testsuite_allocator.h: Revert last change.
