Re: RFA: libjava seems to miss some files for win32

  Hmmm... it is supported since win2k.  I imagine DGJPP runs on 9x targets,
and believe it or not there are still some Cygwin users on NT4.  I would think
it needs an autoconf test, and on platforms that don't support CryptoAPI it
should probably throw an exception to indicate 'not implemented' rather than
(e.g.) fall back to rand(), but that's a policy decision for the Java
maintainers really.

  Ouch, yes!  You'll probably be best off replacing those with something based
on uintptr_t, which may or may not have a j* equivalent already.

    cheers,
