Bison 2.0 available from alpha.gnu.org

[Paul Eggert]

Bison version 2.0 is now available.  It is a relatively small change
since the last official release (1.875), so we feel we've converged on
the "new" version of Bison ("new" compared to Bison 1.35, that is).

We're making Bison 2.0 available via alpha.gnu.org at first, to see
whether there's any packaging problem or silly compatibility issue
like that.  Our intention is to copy 2.0 to the official release area
in ftp.gnu.org soon, if no immediate problems are discovered in it.

Here is the URL:

ftp://alpha.gnu.org/gnu/bison/bison-2.0.tar.gz

Here is the MD5 checksum:

Bison is a parser generator that is compatible with Yacc.
Please see <http://www.gnu.org/software/bison/> 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:

   wget ftp://alpha.gnu.org/gnu/bison/bison-2.0.tar.gz
   gunzip <bison-2.0.tar.gz | tar xf -
   cd bison-2.0
   ./configure
   make
   make check

We particularly appreciate tests on unusual hosts.

Please report bugs to <address@hidden>.

Here is a list of user-visible changes in version 2.0, compared to
the previous test version.  Please see the NEWS file for the complete
list of changes since the last official release.

  - Bison-generated parsers no longer default to using the alloca function
    (when available) to extend the parser stack, due to widespread
    problems in unchecked stack-overflow detection.  You can "#define
    YYSTACK_USE_ALLOCA 1" to require the use of alloca, but please read
    the manual to determine safe values for YYMAXDEPTH in that case.
