This is the Perl5 equivalent of the MNT_NOSUID patch that was put into
/usr/bin/perl a while ago. It works with 5.003 and 5.004-tobe. I can't test it on freefall (I don't have a setuid script to play with) but it works at home. I'll test on thud later. Every setuid script found on a partition mounted "nosuid" will not be executed and "Permission Denied" will be displayed. It won't be in soo-to-be-released 5.004 because it is not a FreeBSD speciific problem but it will be dealt with in 5.004_01 (maintenance release). Obtained from: Jörg's patch (edited for Perl5 by me).
