errors, not necessarily a pointer such that (intptr_t)pointer is -1.
Also fix the style bug that the cast was not followed by a space.
This style of this file is now perfectly non-KNF for this cast too.
In "nroff" mode, italic font renders as an underlined text, which
makes it indistinguishable from the bold text on color monitors
(cons25 terminal type), yet it requires the less(1)'s -R option.
(Refer to the new grotty(1) manpage for details.)
So turn off the color support for now (when generating catpages),
until we figure out what do we do with this new feature. I have
a patch for grotty(1) that tells it to use the "reverse video"
attribute to render the italic font. Once this is accepted, we
can turn color support back on (if there won't be any objections
from the community).
manpages in machine-specific subdirectories (like man4/i386/) to
"../". This change didn't propagate here resulting in a loss of
whatis(1) database entries. Fix this.

The code will be fixed for all known security vulnerabilities,
and a make.conf(5) knob (ENABLE_SUID_MAN) will be provided for
those who still want it installed setuid for whatever reasons.
The catpaging and setuidness features of man(1) combined make
it vulnerable to a number of security attacks. Specifically,
it was possible to overwrite system catpages with arbitrarily
contents by either setting up a symlink to a directory holding
system catpages, or by writing custom -mdoc or -man groff(1)
macro packages and setting up GROFF_TMAC_PATH in environment
to point to them. (See PR below for details).
This means man(1) can no longer create system catpages on a
regular user's behalf. (It is still able to if the user has
write permissions to the directory holding catpages, e.g.,
user's own manpages, or if the running user is ``root''.)
To create and install catpages during ``make world'', please
set MANBUILDCAT=YES in /etc/make.conf. To rebuild catpages
on a weekly basis, please set weekly_catman_enable="YES" in
/etc/periodic.conf.

back (as of man.c,v 1.45), change the meaning of the -m option
from poorly documented and badly coded "alternate system" to a
much more useful "different architecture for the same system".
