Even in non par grades when parallel marking is not enabled?  What
pthreads calls could we make then then?   I think libc on MinGW-w64
requires winpthread to support some C11 features, so maybe it's always
needed on that system, but shouldn't it remain possible to build non
.par grades on plain MinGW without requiring pthreads?
