Hi Wylda,

Are you doing that with wineinstall? This doesn't affect normal
./configure && make, only ./tools/wineinstall.

That said, allowing the user to set it via NPROC or similar would be a
good idea IMO.

Is this what you had in mind? I wasn't sure how to document that you could do:

NPROC=50 ./tools/wineinstall

to force 50 parallel processes.

wineinstall - Add support for parallel builds using 'nproc' to detect cpu count

Parallel builds can greatly reduce the overall build time on modern multi-core processors.

Fall back to two parallel builds in the case where nproc is unavailable, most modern

processors have at least two cores.

Use the 'NPROC' value defined by the environment if it is not null.
