Bison 1.29e released

[Akim Demaille]

Hopefully this version is portable.  Hopefully the test suite is
portable too.  Hopefully the next message will announce the actual
release.

Many thanks to all the people who helped us tuning this beta!

NEWS:
Changes in version 1.29e:

* `--defines' and `--graph' have now an optionnal argument which is the
  output file name. `-d' and `-g' do not change, they do not take any
  argument.

* `%source_extension' and `%header_extension' are removed, failed
  experiment.

* The test suite is more portable.

* Better portability.

Changes in version 1.29:

* The output file does not define const, as this caused problems when used
  with common autoconfiguration schemes.  If you still use ancient compilers
  that lack const, compile with the equivalent of the C compiler option
  `-Dconst='.  autoconf's AC_C_CONST macro provides one way to do this.

* Added `-g' and `--graph'.

* The Bison manual is now distributed under the terms of the GNU FDL.

* The input and the output files has automatically a similar extension.

* Russian translation added.

* NLS support updated; should hopefully be less troublesome.

* Added the old Bison reference card.

* Added `--locations' and `%locations'.

* Added `-S' and `--skeleton'.

* `%raw', `-r', `--raw' is disabled.

* Special characters are escaped when output.  This solves the problems
  of the #line lines with path names including backslashes.

* New directives.
  `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose',
  `%debug', `%source_extension' and `%header_extension'.
