Change 34601 by [EMAIL PROTECTED] on 2008/10/27 08:28:31

        Integrate:
        [ 34595]
        USE_FAST_STDIO can affect behaviour, so list it in -V
        
        [ 34596]
        Cope with brain damage in PerlIO::via, which will let you fclose() the
        same FILE * twice, thanks to it calling out to Perl space inside the
        close call tree, with the underlying PerlIO * already closed, but not
        unlinked.
