*BOOL our_ultow(val, buf, bufsize, radix) - convert binary int to wide
*	char string
*
*Purpose:
*	Converts an int to a wide character string.
*
*Entry:
*	val - number to be converted (int, long or unsigned long)
*	int radix - base to convert into
*	wchar_t *buf - ptr to buffer to place result
*	int bufsize - size of buffer pointed to by buf, in characters
*
*Exit:
*	calls ASCII version to convert, converts ASCII to wide char into buf
*	returns TRUE if char. conversion succeeded, FALSE otherwise.
*
*Exceptions:
