Several of my packages that used to build fine with parallel make now require

I can't find any pattern to explain when the problem occurs and when it doesn't,
but it seems to be due to a change in make, starting with version 4.4. By
default, make now uses a FIFO rather than a pipe in its jobserver
implementation. You can override this with the make flag
--jobserver-style=pipe
In all cases where I've tried this, parallel make works again.
It wouldn't surprise me if there's a bug in Cygwin's FIFO implementation that's
responsible for this, but I haven't yet tried to track it down.
There is some glibc? compatibility issue also with this recommended workaround.
