README.openbsd - Perl version 5 on OpenBSD systems
DESCRIPTION
This document describes various features of OpenBSD that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
OpenBSD core dumps from getprotobyname_r and getservbyname_r with ithreads
When Perl is configured to use ithreads, it will use re-entrant library calls in preference to non-re-entrant versions. There is an incom-
patability in OpenBSD's "getprotobyname_r" and "getservbyname_r" function in versions 3.7 and later that will cause a SEGV when called
without doing a "bzero" on their return structs prior to calling these functions. Current Perl's should handle this problem correctly.
Older threaded Perls (5.8.6 or earlier) will run into this problem. If you want to run a threaded Perl on OpenBSD 3.7 or higher, you will
need to upgrade to at least Perl 5.8.7.

README.freebsd - Perl version 5 on FreeBSD systems
DESCRIPTION
This document describes various features of FreeBSD that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
FreeBSD core dumps from readdir_r with ithreads
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 "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 ) which has been integrated into FreeBSD 4.6.
$^X doesn't always contain a full path in FreeBSD
perl 5.8.0 sets $^X where possible to a full path by asking the operating system. On FreeBSD the full path of the perl interpreter is found
by reading the symlink /proc/curproc/file. There is a bug on FreeBSD, where the result of reading this symlink is can be wrong in certain
circumstances (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). In these cases perl will fall back to the old behaviour of using
C's argv[0] value for $^X.
Perl will no longer be part of "base FreeBSD"
Not as bad as it sounds--what this means is that Perl will no longer be part of the kernel build system of FreeBSD. Perl will still very
probably be part of the "default install", and in any case the latest version will be in the ports system. The first FreeBSD version this
change will affect is 5.0, all 4.n versions will keep the status quo.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
