ignoring close failures

[Nicholas Clark]

This bit of Perl_sv_clear is generating a compiler warning now:

    case SVt_PVIO:
        if (IoIFP(sv) &&
            IoIFP(sv) != PerlIO_stdin() &&
            IoIFP(sv) != PerlIO_stdout() &&
            IoIFP(sv) != PerlIO_stderr())
        {   
            io_close((IO*)sv, FALSE);
        }


Should we really be ignoring close failure here? Would it be better to
issue a lexical warning? If so, what category? And what text?
