/*
 * This file supplies declarations for extended locale routines, as
 * originally delivered by MacOS X.  Many of these things are now
 * officially part of XPG7.  (Note that while the interfaces are the
 * same as MacOS X, there is no shared implementation.)
 *
 * Those declarations that are part of XPG7 are provided for the in the
 * XPG7-specified location.  This file lists just the declarations that
 * were not part of the standard.  These will be useful in their own right,
 * and will aid porting programs that don't strictly follow the standard.
 *
 * Note that it is an error to include this file in a program with strict
 * symbol visibilty rules (under strict ANSI or POSIX_C_SOURCE rules.)
 * If this is done, the symbols defined here will indeed be exposed to your
 * program, but those symbols that are part of the related standards might
 * not be.
