* Modified for IKVM by Jeroen Frijters on May 22, 2007.
*
* This is a merged version of the Windows & Solaris platform specific versions.
* Since the IKVM class library binary can be used both on Windows and on *nix,
* I've merged the platform specific classes into a generic class that at
* runtime determines if it runs on Windows or not.
