Java push parser

[Dennis Heimbigner]

I am submitting code to
add push parsing support for
Java through Bison.

The relevant code can be obtained
using this url:
    http://www.unidata.ucar.edu/staff/dmh/push.tar
That tar file contains three files:
1. lalr1.java - revised skeleton to add push parsing support
2. javapush.at - tests for the push parsing. It will
                 require adding the line
                   m4_include([javapush.at])
                 to the file tests/testsuite.at
3. push.texi - text to be inserted somewhere into the
               bison documentation. It gives a brief
               description on using the push features.

The lalr1.java is consistent with the lalr1.java in the master
git repository as of 1/15/2013.

Report any bugs to dmh at unidata.ucar.edu
