Hello,

This patch adds dummy implementation for 
gnu/java/security/jce/prng/natVMSecureRandomWin32.cc file for Win32 build. 
It throws just an exception for not supporting this method.

ChangeLog

2009-07-24  Kai Tietz  <kai.tietz@onevision.com>

        * gnu/java/security/jce/prng/natVMSecureRandomWin32.cc: New Win32
        specific implementation.

Tested for i686-pc-mingw32. Ok for apply to trunk?


Cheers,
Kai
