	* libc/locale/lmonetary.h: Make C++-safe.
	(__monetary_load_locale): Change declaration.
	* libc/locale/lnumeric.c (__numeric_load_locale): Take additional

	consumption by strftime and strptime.
	(__time_load_locale): Change declaration.
	* libc/time/strftime.c: Change documentation to reflect changes to
