Re: parallel make

Rich, First off, if you're willing to forgo the ability to access UNC paths from Cygwin, you can set your Cygdrive prefix to '//' to address the drives in the same way you did in your old GNU toolset (see ). Secondly, why not use Cygwin perl? Th

Re: parallel make

make -j does work in cygwin, to an extent. If you try to use too many processes, cygwin seems to flip out. -j20 does seem to work fine though (it only starts acting strang around -j100). On my large build system, we have a slow disk, and I find that when the disk cache is empty, -j4 speeds it
