Update to 1.4.6:

Version 1.4.6 - 25 August 2006, by Eric Blake  (CVS version 1.4.5a)

* Fix buffer overruns in regexp and patsubst macros when handed a trailing
  backslash in the replacement text, or when handling \n substitutions
  beyond the number of \(\) groups.
* Fix memory leak in regexp, patsubst, and changeword macros.
* The format macro now understands %F, %g, and %G.
* When loading frozen files, m4 now exits with status 63 if version
  mismatch is detected.
* Fix bugs that occurred when invoked with stdout or stderr closed,
  and detect write failures to stdout or to the target of the
  debugfile macro.  In particular, the syscmd and esyscmd macros can
  no longer interfere with the debug stream or diversions.
* The m4exit macro now converts values outside the range 0-255 to 1.
* It is now an error if a command-line input file ends in the middle of a
  comment, matching the behavior of mid-string and mid-argument
  collection.
* The dnl macro now warns if end of file is encountered instead of a
  newline.
* The error message when end of file is encountered now uses the file and
  line where the dangling construct started, rather than `NONE:0:'.
* The debugmode and __file__ macros, and the -s/--synclines option, now
  show what directory a file was found in when the -I/--include option or
  M4PATH variable had an effect.
* The changequote and changecom macros now work with 8-bit characters, and
  quotes and comments that begin with `(' are properly recognized
  following a word.
* The new macro __program__ is added, which allows the input file to issue
  an error message that resembles messages from m4.  Warning and error
  messages have been reformatted to comply with GNU Coding Standards.
* The errprint, m4wrap, and shift macros are now recognized only with
  arguments.
* The index, substr, translit, regexp, and patsubst macros now produce
  output when given only one argument, but still warn about a missing
  second argument.
* The patsubst macro now reliably finds zero-length matches at the end
  of a string.
