-DUSE_THREADS is needed to enable multithreaded build mode; without it you get a single-threaded build, which would only be useful if all you ever wanted to do is run one such 1-thread job per core....

@OP: Suggest you try a tiny M(p) example: n = M(11) = 2^11-1 = 23*89. The 2 prime factors have p-1 decompositions:
p = 23: p-1 = 2*11
q = 89: q-1 = 2^3*11
So taking E = 2*11 in p-1 stage 1...
