 1.12  28-May-2007  tls Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.
 1.11  08-Oct-1998  wsanchez Init style to quiet compiler.
Allow zcat hard link to compress rather than using zcat.sh wrapper; same as uncompress.
Don't install zcat, however; gzcat seems to be living in /usr/bin/zcat at the moment.
 1.10  08-Nov-1997  lukem remove WARNS?=1
 1.9  15-Sep-1997  lukem branches: 1.9.2;
* cleanup for WARNS=1
* deprecate register
* rindex -> strrchr
* fix .Nm usage
 1.8  24-Mar-1997  christos - Makefile cleanups
 1.7  18-Oct-1996  thorpej Use ${INSTALL}.
 1.6  26-Mar-1995  glass new rcsid format. what is the format for shell scripts
 1.5  17-Oct-1994  cgd don't install zcat (as it's now done by gzip), and excise the zcat sections
from the man page. add a xref to zcat(1). delete nothing, so that
people who want to avoid zcat can.
 1.4  13-Jun-1994  cgd branches: 1.4.2;
clean up import, add rcsid's.
 1.3  23-Oct-1993  jtc Both compress and gzip installed themselves as "zcat". I've changed the
makefiles so only gzip is installed as zcat (and now uncompress) because
gzip is faster than compress and it is able to detect corrupted files.
 1.2  31-Jul-1993  mycroft Add RCS indentifiers.
 1.1  21-Mar-1993  cgd branches: 1.1.1;
Initial revision
 1.1.1.2  13-Jun-1994  cgd new compress from Lite
 1.1.1.1  21-Mar-1993  cgd initial import of 386bsd-0.1 sources
 1.4.2.1  17-Oct-1994  cgd from trunk.
 1.9.2.1  08-Nov-1997  lukem sync with trunk (approved by thorpej)
