Updates to JPL

I had a chance to mess around with the JPL code today (but I didn't get
in very deep).  

* I have incorporated the code from the latest.tar.gz Perl distribution.

* On Win32, I tried to work with ActivePerl 5.6 and JDK 1.2.2.

  I fixed the C++ style function calls that were wrapped in a #ifdef WIN32
  block - these seem to work now as  (*env)->FUNCTIONNAME(env, args) where
  I previously had these env->FUNCTIONAME(args) under WIN32.

  However, a number of errors still occur under Win32:

  Stop.

* On Linux, I worked with RedHat 6.1, the Perl that comes with RedHat 6.1,
  and IBM JDK 1.1.8.  The instructions in README.JUST-JNI work through
  'make test' and 'make install', but I have not tried to stress it too
  much.

The latest changes are now in the CVS archive, and you can get
instructions for accessing it at:
