*lconv.c - Contains the localeconv function
*
*       Copyright (c) 1988-2001, Microsoft Corporation. All rights reserved.
*
*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_*.
*       04-06-93  SKS   Replace _CRTAPI* with __cdecl
*       09-15-93  CFW   Use ANSI conformant "__" names.
*       04-14-94  GJF   Made definitions of __lconv and __lconv_c conditional
*                       on ndef DLL_FOR_WIN32S. Include setlocal.h.
*       01-07-95  CFW   Mac merge.
*       05-13-99  PML   Remove Win32s
*       05-17-99  PML   Remove all Macintosh support.
