*
*Purpose:
*	Contains the localeconv() function.
*
*Revision History:
*	03-21-89   JCR	Module created.
*	06-20-89   JCR	Removed _LOAD_DGROUP code
*	03-14-90   GJF	Replaced _cdecl _LOAD_DS with _CALLTYPE1 and added
*			#include <cruntime.h>. Also, fixed the copyright.
*	10-04-90   GJF	New-style function declarator.
*	10-04-91   ETC	Changed _c_lconv to _lconv (locale support).
*			_lconv no longer static.
*	12-20-91   ETC	Changed _lconv to _lconv_c (C locale structure).
*			Created _lconv pointer to point to current lconv.
*	02-08-93	CFW	Added _lconv_static_*.
