Even on linux, I don't find it satisfactory to run make check without
limiting processes to number of cores.  On cygwin and wsl, make check
seems to run into deadlocks or at least disastrous timeouts when running
multiple processes.  With a single process, cygwin runs it more reliably
than wsl does.  Conversely, sometimes (rarely) wsl can run make check-c
and make check-fortran simultaneously.
So it takes typically 2 full days to build and make check on cygwin.
