8700b24578 Update to upstream version 2.7
The most notable new feature is support for processing multiple
files in one invocation. There is also support for more make-friendly
exit statuses.

The most notable bug fix is #line directives now include the input
file name.

94f94d90e4 Update to upstream version 1.338
Fix a long-standing cpp compatibility bug: The -DFOO argument
(without an explicit value) should define FOO to 1 not to the empty
string.

Add support for CRLF newlines, based on a suggestion from Mark Rushakoff.

d3169e6c49 Add a -o outfile option, which can be used to specify an output file. The
file can safely be the same as the input file.  Idea from IRIX unifdef(1).
This version fixes a bug in the NetBSD unifdef which refuses to
write to a -o outfile which does not exist.

0960dfee41 Update unifdef to my upstream version 1.188
Main highlights:

(A) The new -B option compresses blank lines around a deleted section
    so that blank lines around "paragraphs" of code don't get doubled.

(B) Lenient evaluation of && and || so that #if expressions can be
    evaluated even when some of their sub-expressions cannot be.

(C) The evaluator can now handle macros with arguments.

(D) Portability fixes, especially for unifdefall.

dc5d130c24 Sync with upstream:
Allow the user to run unifdef without defining any symbols. This is
useful in conjunction with the -k flag.
Fix a bug in the -s handling code that would have caused out-of-bounds
array accesses.
Add a -n option to insert #line directives in the output.
Ignore comment markers inside string and character literals
(bug reported by Amos Shapira <amos.shapira@netregistry.com.au>).
More accurate copyright notices.

d707a4320d Sync with upstream again:
* Be less strict about multi-line preprocessor directives (e.g. those
    with comments hanging off the right-hand end) since they're more
    of a problem in practise than I expected. Prompted by phk.

* Fix the handling of "ignore" symbols.

* Style pedantry from OpenBSD and Ted Unangst <tedu@stanford.edu>,
    including some whitespace fixes and removal of strcpy()
    (and not including excessively strict KNF enforcement).

* Fix some typos and terminological inconsistencies.

fd4a464ac4 Sync with up-stream version, including a number of bug-fixes:
* The partial-evaluation of #elif sequences was broken and the
spaghetti logic of its implementation was too hard to understand.
I've re-done it using a straight-forward table-driven push-down
automaton.

* The pre-processor line parser did not allow for all of the weird
places that people might put comments, which could have caused it
to add syntax-errors to the output by removing a #if line containing
the start- or end-marker of a comment.

* The lexer didn't need to special-case the handling of string-literals
or character-constants, but it did need to learn about line-continuations
(backslash-newline).

* The input routine was buggy and bit-rotten and trivially replacable
with fgets(). I've also made the program static- and const-safe and
improved the presentation-order. The formatting of the state-transition
tables remains non-stylish.

e90165a4c9 It is probably a bad idea to unconditionally process directives with
constant controlling expressions: in particular, removing #if 0 sections
is considered "rude". This commit changes the default so that such
things are passed through unchanged, and the old behaviour can be had
with the -k "kill konsts" flag.

94a883658e Upgrade unifdef:
* It now knows about the existence of #elif which would have
    caused it to produce incorrect results in some situations.

  * It can now process #if and #elif lines according to the
    values of symbols that are specified on the command line.
    The expression parser is only a simple subset of what C
    allows but it should be sufficient for most real-world
    code (it can cope with everything it finds in xterm).

  * It has an option for printing all of the symbols that might
    control #if processing. The unifdefall script uses this
    option along with cpp -dM to strip all #ifs from a file.

  * It has much larger static limits.

  * It handles nested #ifs much more completely.

There have also been many style improvements: KNF; ANSI function
definitions; all global stuff moved to the top of the file; use
stdbool instead of h0h0bool; const-correctness; err(3) instead
of fprintf(stderr, ...); enum instead of #define; commentary.

I used NetBSD's unifdef as the basis of this since it has received
the most attention over the years.

6578739ddb Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
