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.

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.

unifdef: fix invalid array access when nesting limit exceeded
If the number of nested #if blocks exceeds 64, nest() increments the nesting depth and then reports an error. The message includes the line number for the start of the current #if block, which is read from past the end of the relevant array.
Avoid the out-of-bounds read by reporting the error and exiting before the nesting depth has a chance to increase.

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.

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.

Various fixes from upstream, including a bug...
Fix the usage synopsis.
Amend the copyright notice to reflect the fact that there's no Berkeley code left.
Fix a typo in a comment, improve the descriptions of the way we use some global variables (relevant to the bug below), and note that division-by-zero has side effects so the current expression evaluator can't be trivially extended to arithmetic in its current design.
Avoid hitting an abort(); /* bug */ when in "text mode" (i.e. ignoring comment state) by updating the line parser state properly.

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.

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.

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.

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.
