 * A simple tool to output all the installed locales on a Windows machine, and
 * corresponding Java default locale/file.encoding using PrintDefaultLocale
 *
 * WARNING:  This tool directly modifies the locale info in the Windows registry.
 * It may not work with the Windows versions after Windows XP SP2.  Also,
 * if the test did not complete or was manually killed, you will need to reset
 * the user default locale in the Control Panel manually. This executable has
 * to be run with the "Administrator" privilege.

 * Usage: "deflocale.exe <java launcher> PrintDefaultLocale
 *
 * How to compile: "cl -DUNICODE -D_UNICODE deflocale.c user32.lib advapi32.lib"
