    This patch fixes, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80188
    which reports that the char* pointer reason is not being translated
    properly when the error message from the function,
    maybe_complain_about_tail_call arises. Fix it by wrapping it in the
    N_ macro to translate to the proper language of the user. No new
    test cases are required due to the triviality of the bug.
