Bison test version 1.875e is now available. It contains mostly bug
fixes from the previous test version. Our intention is to generate a
new official release soon, based on feedback from this test version.

Bison is a parser generator that is compatible with Yacc.
Please see <> for more info about Bison.

To try this test version, please make sure you have GNU m4 1.4
installed (version 1.4.2 is best, as it has many bugs fixed),
and then execute the following shell commands or their equivalents:

      gunzip <bison-1.875e.tar.gz | tar xf -
      cd bison-1.875e
      make check

We particularly appreciate tests on unusual hosts.

Please report bugs to <>.

Here is a list of user-visible changes in version 1.875e, compared to
the previous test version. Please see the NEWS file for the complete
list of changes since the last official release.

* New directive: %initial-action.
    This directive allows the user to run arbitrary code (including
    initializing @$) from yyparse before parsing starts.

* The option `--report=lookahead' was changed to `--report=look-ahead'.
    The old spelling still works, but is not documented and will be

* Error token location.
    During error recovery, the location of the syntax error is updated
    to cover the whole sequence covered by the error token: it includes
    the shifted symbols thrown away during the first part of the error
    recovery, and the lookahead rejected during the second part.

* Goto numbers are no longer arbitrarily limited to 16-bit counts.
