xlint: update.

Bring some important updates from NetBSD up to about 2008/04/25.
The main feature is initial support for C99.

This is a very basic update to make it easier to merge new
compiler attirbutes but more updates are likely to follow.

Spelling fixes for usr.bin/

lint: Fix lseek() argument order.

Because SEEK_SET is 0, this seems to have no effect on the generated code.

1) Make usage() as dead2 - it helps the compiler know that some vars
are not used uninitialised.
2) Fix some constness problems.
3) Avoid a signedness problem by casting to size_t. If bn != stuff,
than stuff-1-bn should be > 0.

Pass "-Wtraditional -Wno-system-headers" to compiler as two separate
arguments. GCC4 was unhappy with them combined, while GCC 3.4 did
not care.

Move the -Wtraditional warning from the global cpp flags to when the -p
(portability warnings) switch is used. Add -Wno-system-headers after it so
that we dont get 500 screenfulls of warnings about #elif in /usr/include.
I'm not entirely happy with this. Maybe cdefs.h shouldn't use #elif and
instead nest #else clauses?

No, forget about rev 1.24. My system wasn't virgin enough when I tested that.
Restore rev 1.23.

Forget about rev 1.23. -$ is now spelled -fno-dollars-in-identifiers.

Submitted by: kan

GCC 3.3's cpplib does not impliment -$ (forbid the use of $ in identifiers).

If the CC environment variable contains multiple words then split
it up into separate exec arguments.

Merge conflicts.

Usage style sweep: spell "usage" with a small 'u'.
Also change one case of blatant __progname abuse (several more remain)
This commit does not touch anything in src/{contrib,crypto,gnu}/.

FreeBSD prior to 4.4-RELEASE and older versions of 5.0-CURRENT do
not have setprogname(3) and getprogname(3), and we need to build
lint(1) as a cross-tool to bootstrap. Versions from lib/libc/gen
can't be compiled either.

PR: bin/36747

Later versions of gcc object very strongly to the -C flag being passed
as -CC. It makes no difference to gcc in the tree, but this change is
necessary for gcc-3.1 to work.

Try harder to lint without nonstandard stuff.

Completeley revert this to the vendor code. This is in preparation to
doing some fixing...

Merge conflicts, fix Makefiles and remove (re)moved file(s).

WARNS=2 fixes.

Expand x{malloc,calloc,realloc,strdup} in-place.
(even found some unchecked naked uses)

Keep my dirty paws off of the $NetBSD$ id's. They're tabbed and should
remain so.

Submitted by: bde/obrien

Aesthetics: fix placement of $NetBSD$ (use space instead of tab)

Properly constify the rcsid[].

Change uses of mktemp() to mkstemp().

Call cc -E, not cpp, this allows lint to be unaware of any
machine-dependent defines that cc(1) may normally define.

Change fork() to vfork() and exit() to _exit().

Reuse temporary file so that multiple files passed can be processed without
problems.

Fix lint for the new cpp. Lint is still broken in other ways, but
this at least allows the use of lint -i on single files again.

Fiddled rcsid to satisfy commitprep.pl; the original NetBSD tag
is still in the comments.

Use __XSTRING() from cdefs.h instead of rolling my own.

I may have forgotten to upgrade this value, but that will never happen
again. (Fully clone the value of __FreeBSD__ from the compiler.)

__FreeBSD__ is also used here.

Forgotten by: Lots of people.
Pointed out by: make world.

Cope with the possibility of __FreeBSD__ = 3

General -Wall warning cleanup, part I.
Submitted-By: Kent Vander Velden <graphix@iastate.edu>

Well, Jochen adopted most of my submissions. So only the different
style of error reporting (i prefer gcc style to be consistent with the
compiler) is left, plus a minor nit he's most likely been overlooking.

There are still problems with bootstrapping, and you should expect
troubles when linting libc...

This commit was generated by cvs2svn to compensate for changes in r12099,
which included commits to RCS files with non-trunk default branches.

Jochen Pohl's lint(1) from NetBSD. Yet another import.

This is just a vendor import by now. I'll wait until i'll get the
imported files back via CTM before applying the FreeBSD patches.
Don't use it yet.
