Update to 1.4.7:

Version 1.4.7 - 25 September 2006, by Eric Blake  (CVS version 1.4.6a)

* Fix regression from 1.4.5 in handling a file that ends in a macro
  expansion without arguments instead of a newline.
* The define and pushdef macros now warn when the first argument is not
  a string, rather than silently doing nothing.
* Standard input can now be read more than once, as in 'm4 - file -', and
  is not closed until all wrapped text is handled.  This makes a
  difference when stdin is not a regular file, and also fixes bugs when
  using the syscmd or esyscmd macros from wrapped text.
* When standard input is a seekable file, the m4exit, syscmd, and esyscmd
  macros now restore the current position to the next unread byte rather
  than discarding an arbitrary amount of buffered data.
* SysV command-line compatibility is no longer a goal of GNU M4; the
  focus will be instead on POSIX compatibility.  This release continues to
  support previous usage, but adds warnings in areas which will allow a
  future version of GNU M4 to use its own extensions without being tied to
  the SysV command line interface.
* The no-op compatibility command line options -B, -N, -S, -T, and
  --diversions may be withdrawn or assigned new meanings in future
  releases, so they now issue a warning if used.
* A new command line option -i replaces the compatibility -e as the
  short spelling of --interactive, for consistency with other GNU tools; a
  warning is issued if the old spelling is used, and it may be assigned new
  meaning in future releases.
* A new command line option --debugfile replaces the options -o and
  --error-output as the preferred spelling.  The old options were
  misleading in their names and inconsistent with other GNU tools; they are
  still silently accepted, but no longer documented in --help, and may be
  assigned new meanings in future releases.

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.

Fix PLIST for non-standard GNU_PROGRAM_PREFIX settings.

Update to 1.4.5:

Version 1.4.5 - 15 July 2006, by Eric Blake  (CVS version 1.4.4c)

* Fix sysval on BeOS, OS/2, and other systems that store exit status
  in the low-order byte.  Additionally, on Unix platforms, if syscmd was
  terminated by a signal, sysval now displays the signal number shifted
  left by eight bits, to match traditional m4 implementations.
* The maketemp macro is no longer subject to platform limitations (such as
  26 or 32 max files from a given template).
* Frozen files now require that the first directive be V (version), to
  better diagnose version mismatch.  Additionally, if the F directive
  (builtin function) names an unknown builtin that existed in the m4 that
  froze the file but not in the current m4 (for example, changeword), the
  warning is deferred until an attempt is made to actually use the
  builtin.  This allows downgrading from beta m4-1.4o to stable m4-1.4.5
  without breaking autoconf.
* The format and indir macros are now recognized only with arguments.
* The eval macro no longer crashes on x86 architectures when dividing the
  minimum integer by -1.
* On systems with ecvt and fcvt, format no longer truncates trailing
  zeroes on integers printed with %.0f.  On systems without these
  functions, format is no longer subject to a buffer overflow that
  permitted arbitrary code execution.
* On native Windows builds, the macro __windows__ is provided instead of
  __unix__.  Likewise, on OS/2 builds, the macro __os2__ is provided.  This
  allows input files to determine when syscmd might behave differently.
* Fix bug in 1.4.3 patch to use \n line-endings that did not work for
  cygwin.
* When given the empty string or 0, undivert is now documented as a no-op
  rather than closing stdout, warning about a non-existent file, or trying
  to read a directory as a file.
* Many documentation improvements.  Also, the manual is now distributed
  under FDL 1.2, rather than a stricter verbatim-only license.
* Raise the -L (--nesting-limit) command line option limit from 250 to
  1024.
* The decr, incr, divert, m4exit, and substr macros treat an empty number
  as 0, issue a warning, and expand as normal; rather than issuing an error
  and expanding to the empty string.
* The eval macro now treats an empty radix argument as 10, handles radix 1,
  and treats the width argument as number of digits excluding the sign,
  for compatibility with other m4 implementations.
* The ifdef, divert, m4exit, substr, and translit macros now correctly
  ignore extra arguments.
* The popdef and undefine macros now correctly accept multiple arguments.
* Although changeword is on its last leg, if enabled, it now reverts to the
  default (faster) regexp when passed the empty string.
* The regexp and substr macros now warn and ignore a trailing backslash in
  the replacement, and warn on \n for n larger than the number of
  sub-expressions in the regexp.

Version 1.4.4b - 17 June 2006, by Eric Blake  (CVS version 1.4.4a)

* Fix a recursive push_string crashing bug, which affected changequote of
  three or more characters on some compilers.
* Use automake to fix build portability issues.
* Fix a recursive m4wrap crashing bug.
* Fix a 1 in 2**32 hash crashing bug.
* Tracing a macro by name is now persistent, even if the macro is
  subsequently undefined or redefined.  The traceon and traceoff macros no
  longer warn about undefined symbols.  This solves a crash when using
  indir on an undefined macro traced with the -t option, as well as an
  incorrect result of ifdef.  Furthermore, tracing is no longer transferred
  with builtins, solving the bug of "m4 -tm4_eval" failing to give trace
  output on the input "define(`m4_eval',defn(`eval'))m4_eval(1)".
* Fix a crash when a macro is undefined while collecting its arguments, by
  always using the definition that was in effect before argument
  collection.  This behavior matches the C pre-processor, and means that
  the sequence "define(`f',`1')f(define(`f',`2'))f" is now documented to
  result in "12", rather than the previously undocumented "22".
* Update the regex engine to fix several bugs.
* Fix a potential crash on machines where char is signed.

Log message:
* Honor PKGINFODIR.
* List the info files directly in the PLIST.

Log message:
Point MAINTAINER to pkgsrc-users@NetBSD.org in the case where no
developer is officially maintaining the package.

The rationale for changing this from "tech-pkg" to \ 
"pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list).  Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

Log message:
Ran "pkglint --autofix", which corrected some of the quoting issues in
CONFIGURE_ARGS.

Log message:
Fixed pkglint warnings. The warnings are mostly quoting issues, for
example MAKE_ENV+=FOO=${BAR} is changed to MAKE_ENV+=FOO=${BAR:Q}. Some
other changes are outlined in
