@@ -17,23 +17,25 @@ When perl is configured to use ithreads, it will use re-entrant library calls
 in preference to non-re-entrant versions.  There is a bug in FreeBSD's
 C<readdir_r> function in versions 4.5 and earlier that can cause a SEGV when
 reading large directories. A patch for FreeBSD libc is available
-(see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 )
+(see L<http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631> )

-perl 5.8.0 sets C<$^X> where possible to a full path by asking the operating

+perl sets C<$^X> where possible to a full path by asking the operating

+C<sysctl> with C<KERN_PROC_PATHNAME> if that is supported, else by reading

 In these cases perl will fall back to the old behaviour of using C's
