One of my grammars that has been working every intermediate build
doesn't work with this one. Here are some of the error messages I get
while running org.antlr.Tool.

     [java] error(100): MathLexer.g:0:0: syntax error: assign.types:
<AST>:0:0: unexpected AST node:
     [java] error(100): MathLexer.g:0:0: syntax error: assign.types:
<AST>:0:0: expecting BLOCK, found ''
     [java] error(100): MathLexer.g:0:0: syntax error: assign.types:
<AST>:0:0: unexpected AST node:
     [java] error(100): MathLexer.g:0:0: syntax error: define:
<AST>:0:0: unexpected AST node:
     [java] error(10):  internal error: MathLexer.g :
java.lang.NullPointerException

I can send you the grammar files if you'd like to see them.
