patch for YAXX: Yacc extended to XML

[Yijun Yu]

The attached patch for bison CVS tree
        http://www.cs.toronto.edu/~yijun/yaxx-patch.tar.gz
is initiated from the "YAXX" project.  It outputs the internal syntax tree
of a program into an XML document named "yaxx.xml". The XML document
complies to the DTD "yaxx.dtd" that is also generated from the YACC
grammar. In addition, the original program can be reconstructed from the
syntax tree through a simple "yaxx.xsl" transformation.

For detail description of YAXX project and examples, please refer to the
following website:

BTW, the patch does not work very well for very large program because the
whole XML document is kept in memory before it is written out. So it may
be necessary to enable with a special switch (TODO).
