 * Based on code extracted from VRPN 07.22 for use as a minimal test case
 *
 * Attempts to compile a difficult bit of code against the Mac
 * HID API, as two different types have been required in the callback
 * function (UInt32 and uint32_t) and testing is the best way to know
 * which one is correct for a given system.
