 * Made numerous other modifications to support PMD.
 *
 * Tom Copeland, 6/02
 * ===================================================================
 * This file is a modified version of one originally found in the
 * VTransformer Examples directory of JavaCC1_1. It has been
 * modified to accept Java source code for Java 1.2. Basically,
 * this means a new key word was added, 'strictfp', and that keyword
 * added to the appropriate productions and LOOKAHEADs (where other,
 * similar keywords are listed as possible choices). This involved
 * changing 11 lines.
 *
 * Some other minor changes were made, which can be found by doing
 * a search on 'DW, 7/99'.
 *
 * The goal of this effort was for the grammar to be able to parse
 * any legal Java 1.2 source code. It does not reject all illegal
 * cases, but neither did the original. Plus, when it comes to
 * the new 'strictfp' keyword, the Java Compiler from Sun (JDK1.2.1)
 * also does not reject all illegal cases, as defined by the
 * "Updates" document found at
 *       http://java.sun.com/docs/books/jls/strictfp-changes.pdf
 * (see the testcases.txt file for details).
