+       test defs: fix 'javac' requirement for older JDK versions
+       The Java compiler from JDK 1.5 (and presumably earlier versions)
+       cannot handle the `-version' option by itself; and while it does
+       print the version number, it then errors out with an usage error:
+         $ javac -version
+         javac 1.5.0_22
+         javac: no source files
+         Usage: javac <options> <source files>
+         ...
+       Luckily, adding the `-help' option to the `javac' invocation
+       seems to fix this problem.
+       * tests/defs.in (javac): Pass also the `-help' option to the
+       `javac' program.  Add a comment explaining why it is needed.
+       Report from Ralf Wildenhues.

        test defs: new requirement for the default java compiler
        * tests/defs.in (for tool in $required): New requirement 'javac'.
        * tests/java.test: Use it instead of ad-hoc configure check.
