Remove inlining of functions that are used mostly in different object files.
This gets rid of gnu89 style inlining. Also silence gcc by assigning two
variables NULL. This lets use to remove NO_WERROR.

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

Obtained from: DragonFlyBSD

Move the MAX macro to a util.h so it becomes usable in other modules.

Two new functions: Buf_Data() returns a reference to the data in
the buffer and Buf_AppendBuf() appends a copy of one buffer to another
buffer.

Patch: 7.146,7.147

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

Create a new function Buf_Peel that returns the string from inside
a Buffer and frees the Buffer.

Introduce Buf_StripNewLines() and use it where appropriate.

Invent a Buf_AppendRange function that appends a non-NUL-terminated string
given by a pointer to the start of the string and a pointer one behind
the end.

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

Invent a Buf_Append function to append a NUL-terminated string
and use it thoughout the code.

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

Rewrite of the buf code:
- convert Buf_AddByte from a macro to a function
- move #define's into the header file
- remove unused field in struct Buffer
- remove size fields - they can be easily computed
- inline Buf_OvAddByte

None of the users of Buf_Discard used it to get rid of only a part of
the buffer. So replace Buf_Discard by Buf_Clear which just gets rid
of the entire contents.

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

Remove a couple of unused buffer functions.

Convert several typedefs from beeing pointers to structs to be the structs
itself. This will ease constification (think of what 'const Ptr foo'
means if Ptr is a pointer to a struct).

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somewhat outdated).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).

Remove an extra space.

Put macro arguments in paranthesis.

Submitted by: johan

Make sizes to be of type size_t and correct function arguments that
should be Byte (as the numerous casts to Byte in the function calls show).

Style: fix indentation, protect macro with do { } while (0).

Checked with: diff on object file.

Style: remove a lot of unnecessary casts, add some and spell the null
pointer constant as NULL.

Checked by: diff -r on the object files before and after

Stylification: missing spaces, extra space after function names, casts
and the sizeof operator, missing empty lines, void casts, extra empty lines.

Checked by: diff on make *.o lst.lib/*.o

Convert make(1) to use ANSI style function declarations. Variable
documentation already adequatedly existed in the description in most
cases. Where it did not, it was added. If no documentation existed
beforehand, then none was added. Some unused dummies for use in the
traversal functions were marked as __unused during the conversion.
Occasionally, local style fixes were applied to lines already being
modified or influenced.

Now make(1) should always build with WARNS=3.

#define<space> -> #define<tab>

Avoid classy use of a variable one time with a constant value.

Fix copyrights, and undo SCS ID damage.

Update SCM ID method.

De'register.

Use __RCSID()

Unduplicate IDs from comments, do $Id -> $FreeBSD$ (submitted-by: bde)

$Id$ -> $FreeBSD$

Merge style- and trivial- only changes from OpenBSD (dated 1999/07/29-19:55+1).

Obtained from: OpenBSD, sometimes indirected from NetBSD; myself

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>
for help in the merge. A 'diff -ur' between Net and
FreeBSD now only contains sccsid-related diffs. :)

Fix for PR# 1095, make's continuation line handling buggy
when used with .elif. Additional fixes include:

- fix continuation line handling when using .for
- plug up a memory leak

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.
