+   * set LD=gcc in the Make file for Linux (fixes bad crash with glibc>=2.1).
+   * clear workspace in main interpreter loop (fixes potential memory leak).
+   * fix off-by-1 memory allocation in signal condition (causes occasional
+     bad crashes).
+   * fix invalid array access in rare case of traceput called with
+     an empty string.
+   * fix rare PARSE VALUE bug which corrupts the expression being parsed.
+   * PARSE bug with arbitrary expressions in template documented.
+   * assignments during parse traced with >=> tag.
+   * sign() function documented.
