make -jN loops on Windows

[Niklas Larsson]

Hi!

I have a hint of what could be wrong.

I looked through my configuration and saw that I used integer-simple. When
I changed it to integer-gmp it blew up with -j4 (it didn't hang though, it
errored out in the linking phase). The build went fine after I reran
without -j.
