/***
*initnum.c - contains __init_numeric
*
* Copyright (c) 1991-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Contains the locale-category initialization function: __init_numeric().
*
* Each initialization function sets up locale-specific information
* for their category, for use by functions which are affected by
* their locale category.
*
* *** For internal use by setlocale() only ***
*
*Revision History:
* 12-08-91 ETC Created.
* 12-20-91 ETC Updated to use new NLSAPI GetLocaleInfo.
* 12-18-92 CFW Ported to Cuda tree, changed _CALLTYPE4 to _CRTAPI3.
* 12-29-92 CFW Updated to use new _getlocaleinfo wrapper function.
* 01-25-93 KRS Change interface to _getlocaleinfo again.
* 02-08-93 CFW Added _lconv_static_*.
* 02-17-93 CFW Removed debugging print statement.
* 03-17-93 CFW C locale thousands sep is "", not ",".
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 04-08-93 SKS Replace strdup() with ANSI-conforming _strdup()
* 04-20-93 CFW Check return val.
* 05-20-93 GJF Include windows.h, not individual win*.h files
* 05-24-93 CFW Clean up file (brief is evil).
* 06-11-93 CFW Now inithelp takes void *.
* 09-15-93 CFW Use ANSI conformant "__" names.
* 09-23-93 GJF Merged NT SDK and Cuda versions.
* 09-15-93 CFW Use ANSI conformant "__" names.
* 04-06-94 GJF Removed declaration of __lconv (it is declared in
* setlocal.h). Renamed static vars, decimal_point
* thousands_sep and grouping to dec_pnt, thous_sep
* and grping (resp.). Made the definitions of these
* conditional on DLL_FOR_WIN32S.
* 08-02-94 CFW Change "3;0" to "\3" for grouping as per ANSI.
* 09-06-94 CFW Remove _INTL switch.
* 01-10-95 CFW Debug CRT allocs.
* 01-18-95 GJF Fixed bug introduced with the change above - resetting
* to the C locale didn't reset the thousand_sep and
* grouping fields correctly.
* 02-06-95 CFW assert -> _ASSERTE.
* 07-06-98 GJF Changed to support new multithread scheme - old lconv
* structs must be kept around until all affected threads
* have updated or terminated.
* 12-08-98 GJF Fixed logic in __free_lconv_num.
* 01-25-99 GJF No, I didn't! Try again...
* 03-15-99 GJF Added __lconv_num_refcount
* 04-24-99 PML Added __lconv_intl_refcount
* 09-08-00 GB Fixed leak of __lconv_intl in init_numeric for single
* thread case.
* 10-12-00 PML Don't call fix_grouping if error detected (vs7#169596)
* 11-05-00 PML Fixed double-free of __lconv_intl (vs7#181380)
