Make spins with THREADS>1 on Win 7

[Edsko de Vries]

Hi all,

Trying to get a build going on Win 7. On both the 32-bit and the
64-bit version running 'sh validate' stalls at

"inplace/bin/mkdirhier" utils/touchy/dist/build/tmp//.

At this point nothing happens, other than that I seem to have 100% CPU
usage; 'ps' only shows two make processes, but no further
subprocesses. Not sure what's going on here. Running 'sh validate
--no-clean' after killing both make processes at this point stalls at
the same point; running it with THREADS=1 seems to resolve the issue.

Anybody any idea what might be going on?
