16 When perl is configured to use ithreads, it will use re-entrant library calls
17 in preference to non-re-entrant versions. There is a bug in FreeBSD's

25 perl 5.8.0 sets C<$^X> where possible to a full path by asking the operating
26 system. On FreeBSD the full path of the perl interpreter is found by reading
27 the symlink F</proc/curproc/file>. There is a bug on FreeBSD, where the
28 result of reading this symlink is can be wrong in certain circumstances
29 (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ).
30 In these cases perl will fall back to the old behaviour of using C's
31 argv[0] value for C<$^X>.

36 part of the B<kernel build system> of FreeBSD. Perl will still very
37 probably be part of the "default install", and in any case the latest
38 version will be in the ports system. The first FreeBSD version this
39 change will affect is 5.0, all 4.n versions will keep the status quo.
