On Windows, PRIO_MAX is not defined so that in compat.h THREAD_PRIORITY_LOWEST is redefined as 20 (which on Windows is higher than real time priority).
The result is the call to SetThreadPriority(THREAD_PRIORITY_LOWEST) in miner.cpp fails and the miner threads actually run at normal priority.
Possibly not a huge issue at this point as I don't expect there are too many wallet miners left but if nothing else cleans up some compiler warning spam.
