/***
*lcnvinit.c - called at startup to initialize lconv structure
*
* Copyright (c) 1993-1997, Microsoft Corporation. All rights reserved.
*
*Purpose:
* initialize lconv structure to CHAR_MAX
*
* 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, the value of CHAR_MAX changes. 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.
*
* 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.
