README.linux - Perl version 5 on Linux systems
DESCRIPTION
This document describes various features of Linux that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
Experimental Support for Sun Studio Compilers for Linux OS
Sun Microsystems has released a port of their Sun Studio compiliers for Linux. As of November 2005, only an alpha version has been
released. Until a release of these compilers is made, support for compiling Perl with these compiler experimental.
Also, some special instructions for building Perl with Sun Studio on Linux. Following the normal "Configure", you have to run make as
follows:
LDLOADLIBS=-lc make
"LDLOADLIBS" is an environment variable used by the linker to link modules "/ext" modules to glibc. Currently, that environment variable
is not getting populated by a combination of "Config" entries and "ExtUtil::MakeMaker". While there may be a bug somewhere in Perl's
configuration or "ExtUtil::MakeMaker" causing the problem, the most likely cause is an incomplete understanding of Sun Studio by this
author. Further investigation is needed to get this working better.

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.

Hello for all,
I am testing the behavior of a 32 bit application running on Solaris 5.10 (SPARC), and realize it reaches 4GB of memory and then crashes.
