try replacing

CYG_ASSERT( ((queue_map & (1<<pri))!=0) == ((!run_queue[pri].empty())!=0), "Map 
and queue disagree");

in rem_thread (mlqueue.cxx), by (please check out the bracketing)

if (! ( ((queue_map & (1<<pri))!=0) == ((!run_queue[pri].empty())!=0) ) ) {
   CYG_ASSERT(0,"Map and queue disagree");
}

put a breakpoint INSIDE if, at CYG_ASSERT, whenever execution reaches that 
figure out the value/state of queue_map, pri and run_queue[pri] .

based on what you observe, work backwards to generate more hints for your situation.

i am assuming - false is 0 in your case and there is no code generation issue.
