Fix things so it *really* won't compile if the environment isn't there.
This commit has been sitting in my to-do list for 2 months. Xditview
should never have been half-removed, so now it's back with a vengance
because we want to keep groff intact as a package.
RCS cannot deal with duplicate tags; the extra one always becomes
inaccessible and useless.
This will prevent the common mistake of specifying the same name
for the vendor tag and the release tag. The FreeBSD CVS repository
already contains zillions of files with this error. We don't need
any more of them.
alias `pcb_cr3' instead. That is still one alias too many, but is convenient
for me since I've replaced the tss in the pcb by a few scalar variables in
the pcb.
need this.
Consider the following code:
case 'O':
output_filename = malloc(strlen(arg)+4);
strcpy(output_filename, arg);
strcat(output_filename, ".tmp");
real_output_filename = arg;
return;
The idea here is to malloc() a buffer big enough to hold the name of
a supplied file name, plus ".tmp". So we malloc() 'size of filename'
bytes plus 4, right? Wrong! ".tmp" is _FIVE_ bytes long! There's a
traling '\0' which strcat() gleefully tacks on _outside_ the bounds
of the buffer. Result: program corrupts own memory. Program SEGVs at
seemingly random times. Bill not like random SEGVs. Bill smash.
Know how I found this? I've been trying to bootstrap -current on my
2.1.0-RELEASE machine at work and I couldn't seem to get libc.a built
because the linker would intermittently blow chunks while executing
things like 'ld -O foo.o -X -r foo.o'. Since this is an initial
bootstrap version of ld, it was linked against the 2.1.0 libc, who's
malloc() behaves differently than that in -current.
Presumeably ld -O doesn't blow up in -current, otherwise someone would
have spotted this already. I don't know if this is a bug or a feature.
Anyway. I'm changing the strlen(arg)+4 to strlen(arg)+5. Bah.
-O filename
Specifies the name of the output file. The file is created as
filename.tmp and when output is complete renamed to filename.
This allows us to:
ld -O ${.TARGET} -x -r ${.TARGET}
file. The field formerly contained random garbage, leading to spurious
differences between otherwise identical executables and libraries.

been loaded, look for a match by device and inode number if the
traditional pathname comparisons don't find a match. This detects
the case in which a library is requested using two different names
which are really links to the same file, and avoids loading it
twice.

matched the filename. Now put the list after the filename. E.g.
filename: vt220keys.1
Keyword: vt220
was: vt220(1), vt220keys(1) - define SHIFTED [...]
now: vt220keys(1), vt220(1) - define SHIFTED [...]

makewhatis.local - start makewhatis(1) only for file systems
physically mounted on the system
Running makewhatis from /etc/weekly for rw nfs-mounted /usr may kill
your NFS server -- all clients start makewhatis at the same time!
So use this wrapper instead calling makewhatis directly.

"-X" must survive, because of references from relocations, don't
qualify the symbol name with the name of the input file. This
saves some string space. It makes libc_pic.a about 2.4% smaller.

DITEM_FAILURE - formerly they would simply act as an implicit "continue",
but this is wrong. If you want this behavior, you should now return
with the DITEM_CONTINUE flag set.
Also make the semantics of DITEM_RESTORE quite a bit different - rather
than restore the screen back to pre-menu state, we restore the menu
itself. This is more correct for a variety of reasons when dealing with
nested menus (whoops!).
robust. The new "fire" actions, while affording signficantly more
interactivity to libdialog, come at a cost - if the fire action trashes
the screen then you're not going to be in Kansas anymore when you
come back to the menu and there had better be considerable extra
smarts in place for coping with such a situation. These changes are my
attempt to do just that.

Also fixed a number of man pages to not abuse the .Xr macro to
display functions and path names and a lot of other junk.
. rename the function to main'gethostname, so it can be called unqualified,
. strip the trailing \0 character, closes PR # bin/1084,
. a better way to express an insane long string.

This solves the problem of being unable to use shared libraries with dots
in their names before the ".so.<version>" code.
This should be brought into -stable.
There are more changes from Paul that look like they should be included,
but they change the format of the hints file, so I'm not going to bring them
in now (but we should in the future).
