* Noteworthy changes in Version 1.4.11 (2008-04-02) [stable]
  Released by Eric Blake, based on git version 1.4.10a

** Security fixes for the -F option, for bugs present since -F was
   introduced in 1.3: Avoid core dump with 'm4 -F file -t undefined', and
   avoid arbitrary code execution with certain file names.

** Fix regression introduced in 1.4.9b in the `divert' builtin when more
   than 512 kibibytes are saved in diversions on platforms like NetBSD
   or darwin where fopen(name,"a+") seeks to the end of the file.

** The output of the `maketemp' and `mkstemp' builtins is now quoted if a
   file was created.  This is a minor security fix, because it was possible
   (although rather unlikely) that an unquoted string could match an
   existing macro name, such that use of the `mkstemp' output would trigger
   inadvertent macro expansion and operate on the wrong file name.

** Enhance the `defn' builtin to support concatenation of multiple text
   arguments, as required by POSIX.  However, at this time, it is not
   possible to concatenate a builtin macro with anything else; a warning is
   now issued if this is attempted, although a future version of M4 may
   lift this restriction to match other implementations.

** Enhance the `format' builtin to parse all C99 floating point numbers,
   even on platforms where strtod(3) is buggy, although the replacement
   function does have the known issue of rounding errors when parsing
   some decimal floating point values.  This fixes testsuite failures
   introduced in 1.4.9b.

** Enhance the `index' builtin to guarantee linear behavior, in spite of
   the surprisingly large number of systems with a brain-dead quadratic
   strstr(3).

** A number of portability improvements inherited from gnulib.
