/*
	wchar.h -- extended multibyte and wide character utilities

	This source code has been placed into the PUBLIC DOMAIN by its author.

	last edit:	1999/08/20	gwyn@arl.mil

	Implements subclause 7.24 of ISO/IEC 9899:1999 (E).

	Unfortunately, it is NOT QUITE CONFORMING, because it #includes
	<stddef.h> to obtain the definitions for wchar_t and size_t,
	<stdint.h> for WCHAR_MIN and WCHAR_MAX, <stdio.h> for FILE, and
	<time.h> for struct tm.  If you plan to include this header in
	a conforming C implementation, you must fix this.  (FILE should
	*not* be defined by this header, although it is needed in the
	declarations!)
