/*
FUNCTION
        <<wcpcpy>>---copy a wide-character string returning a pointer to its end

SYNOPSIS
        #include <wchar.h>
        wchar_t *wcpcpy(wchar_t *<[s1]>, const wchar_t *<[s2]>);

DESCRIPTION
        The <<wcpcpy>> function copies the wide-character string pointed to by
        <[s2]> (including the terminating null wide-character code) into the
        array pointed to by <[s1]>. If copying takes place between objects that
        overlap, the behaviour is undefined. 

RETURNS
        This function returns a pointer to the end of the destination string,
        thus pointing to the trailing '\0'.

PORTABILITY
<<wcpcpy>> is a GNU extension.

No supporting OS subroutines are required.
