Remove unnecessary includes.

Get rid of the ReturnStatus obscuration that was anyway used only
in two places. While here don't bother returning anything from
Lst_Replace - nobody ever checks the return code.

Move the Boolean and ReturnStatus stuff from sprite.h to util.h and
get rid of sprite.h.

Remove debugging code that crept in in the last commit.

Remove Lst_Find() and Lst_FindFrom() now that they aren't needed anymore.

Now that there are no users of Lst_ForEach and Lst_ForEachFrom are left
delete these two macros and all the associated stuff.

Ups. Revert the last commits. These have been committed by accident.

modifier_M: instead of going through the string twice to compute the
size of the buffer we need, just allocate the possible maximum.

Patch: 7.117

Submitted by: Max Okumoto <okumoto@ucsd.edu>

Implement a new macro LST_NEXT which is like Lst_Succ but doesn't check
for its argument to be non-NULL.

Invent the LST_FOREACH macro for looping through a list. In contrast
to the Lst_ForEach function this macro reduces the number of function
calls per invocation by N + 1 (where N is the number of list elements)
and increases code locality thereby increasing readability and
(maybe) performance.

Lst_Append returns void, so the other case of the ? statement
should also be void.

Clean up include files and file including. Split nonints.h into pieces
that get included just where they are needed. All headers include the
headers that they need to compile (just with an empty .c file). Sort
includes alphabetically where apropriate and fix some duplicate commenting
for struct Job, struct GNode and struct Shell by removing one version and
inlining the comments into the structure declaration (the comments have been
somewhat outdated).

This patch does not contain functional changes (checked with md5).

Instead of dynamically allocating list heads allocated them statically
now that their size is only two pointers. This eliminates a lot of calls
to Lst_Init and from there to malloc together with many calls to
Lst_Destroy (in places where the list is obviously empty). This also
reduces the chance to leave a list uninitilized so we can remove more
NULL pointer checks and probably eliminates a couple of memory leaks.

Nobody actually checked the return codes from Lst_Append and Lst_Insert
so don't return anything.

No caller checks the return code from Lst_Remove, so don't return one.
Simplify the algorithm now that circular lists are gone.

Remove return value from Lst_Concat. None of the callers ever checked
it. Remove stuff that was needed for circular lists.

Get rid of the sequential access feature of the lists. This was used
only in a couple of places and all of them except for one were easily
converted to use Lst_First/Lst_Succ. The one place is compatibility
mode in job.c where the it was used to advance to the next command on
each invocation of JobStart. For this case add a pointer to the node to
hold the currently executed command.

Constify the arguments to the list compare function. This temporarily
requires to make a copy of the filename in ReadMakefile and to duplicate
two small functions in suff.c. This hopefully will go away when everything
is constified.

Typedefs of pointers to structs are evil. Make Lst and LstNode typedef of
the structs itself not of pointers to them. This will simplify constification.

Checked by: diff on the object files

Make needs no circular lists so remove them from the list code.

Change a couple of the primitve list functions to be macros. This changes
the semantic of Lst_Datum which formerly returned NULL when the argument
node was NULL. There was only one place in the source that relied on this
so change that place.

Use typedefs for the types of the functions that are passed as arguments
to the list functions for better readability.

Merge the contents of lstInt.h into the public lst.h. This let's us get
rid of a lot of uneccesary casts and temporary variables that have just
obfuscated the code. This also let's us implement a couple of the one-
liner list functions as macros (the first one is Lst_IsEmpty) and
simplify life once we start to throw consts on the code.

There's also no point in #typedef'ing void/char pointers. Accordingly,
rip out ClientData/Address pointers and use standard types.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

O' to be bitten by CVS. Cleanup after import
of Christos' version of make(1) and add Id's.

Set straight by: Bruce Evans and Peter Wemm :)

Merge in NetBSD's changes to make(1). Changes include:

- Add the .PHONY, .PARALLEL, and .WAIT directives
- Added the -B and -m commandline flags
- misc. man page cleanups
- numerous job-related enhancements
- removed unused header file (bit.h)
- add util.c for functions not found in other envs.
- and a few coordinated whitespace changes

Special thanks to Christos Zoulas <christos@netbsd.org>

FreeBSD now only contains sccsid-related diffs. :)

Remove trailing whitespace.

Bring in a number of changes from NetBSD's make, fixing quite a few
problems in the process:

1. Quoting should work properly now. In particular, Chet's reported bash
make problem has gone away.
2. A lot of memory that just wasn't being free'd after use is now freed.
This should cause make to take up a LOT less memory when dealing with
archive targets.
3. Give proper credit to Adam de Boor in a number of files.
