This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.
Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]
Mark known build failures as NO_PIE for now.
The only known runtime failure was rtld.

current version of FreeBSD, this isn't guarenteed by the API. Custom
security modules, or future implementations of the setuid and setgid
may fail.

more sensible/understandable. 'from'->'from_host' 'host'->'local_host'
'fromb'->'frombuf' 'fromhost'->'origin_host' and a local-variable
named 'host'->'hostbuf'. This fixes some compile-time warnings about
local variables shadowing global variables.
Other than renaming variables, the only actual code changes are to call
strlcpy() instead of strncpy() when setting those (renamed) variables,
and that 'from_ip' is now a strdup()-created buffer instead of being a
static buffer compiled in as 1025 bytes.

with BDECFLAGS on, mainly by adding 'const' to parameters in a number
of routine declarations. While I'm at it, ANSI-fy all of the routine
declarations. The resulting object code is exactly the same after
this update as before it, with the exception of one unavoidable
change to lpd.o on freebsd/alpha.
Also added $FreeBSD$ line to lpc/extern.h lpc/lpc.h lptest/lptest.c

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

yet-to-be-built libraries.
Get the default BINDIR correctly (by including ../Makefile.inc recursively.
Override the default it it is wrong.
Don't override defaults when the defaults are correct.
GCC suppresses the warning for ``standard'' header files, but since the
headers do not come from the ``standard'' place in a ``make world'', GCC
doesn't get it.
- Get rid of a lot of the static variables which were shared by
many routines and programs in the suite.
- Create an abstract interface to the printcap database, so that
other retrieval and iteration mechanisms could be developed
(e.g., YP, Hesiod, or automatic retrieval from a trusted server).
- Give each capability a human-readable name in addition to the historic
two-character one.
- Otherwise generally clean up a lot of dark corners. Many still remain.
- When submitting jobs, use the official login name record (from getlogin())
if there is one, rather than reverse-mapping the uid.

overflow patches that were "near" to where these operations are taking
place. The buffer overflows are from OpenBSD. The setuid/seteuid patches
are from NetBSD by way of OpenBSD (they changed them a little), at least from
my read of the tree.
This is the first of a series of OpenBSD lpr/et al merges. It (and them)
should be merged back into 2.2 and/or 2.1 (if requested) branches when they
have been shaken out in -current.
