I tried make -j2, which locked up. "sh validate" used -j but I'm not sure with what N.
It's tantalising if it worked for you! And it worked fine on my old Win7 laptop. Where did you get your mingw/msys installation from? I got mine from http://www.mingw.org/, using the download installer "Mingw-get-setup.exe".
I have also just unravelled another bizarre failure, which I'll describe in a separate email. Sadly resolving the latter does not fix the make -j2 problem.

Hi!
Are you using make -j with or without number of jobs? I tried with make -j4 on my Windows 8 machine and it worked well.
