*charmax.c - definition of _charmax variable** Copyright (c) 1993-2001, Microsoft Corporation. All rights reserved.**Purpose:* defines _charmax** According to ANSI, certain elements of the lconv structure must be* initialized to CHAR_MAX and the value of CHAR_MAX changes when* the user compiles -J. To reflect this change in the lconv structure,* we initialize the structure to SCHAR_MAX, and when any of the users* modules are compiled -J, the structure is updated.** Note that this is not done for DLLs linked to the CRT DLL, because* we do not want such DLLs to override the -J setting for an EXE* linked to the CRT DLL. See comments in crtexe.c.** Files involved:** locale.h - if -J, generates an unresolved external to _charmax* charmax.c - defines _charmax and sets to UCHAR_MAX (255), places* _lconv_init in startup initializer table if pulled in by -J* lconv.c - initializes lconv structure to SCHAR_MAX (127),* since libraries built without -J* lcnvinit.c - sets lconv members to 25.***Revision History:* 04-06-93 CFW Module created.* 04-14-93 CFW Change _charmax from short to int, cleanup.* 09-15-93 SKS Use ANSI conformant "__" names.* 11-01-93 GJF Cleaned up a bit.* 04-28-99 PML Wrap __declspec(allocate()) in _CRTALLOC macro.* 03-27-01 PML .CRT$XI routines must now return 0 or _RT_* fatal* error code (vs7#231220)********************************************************************************/
