Several packages that used to build fine on Cygwin with parallel make
now fail to build. I either get strange errors or a hang. The problems
started with version 4.4 and seem to stem from the fact that make now
uses a FIFO by default instead of a pipe. If I use the flag
'--jobserver-style=pi

I may be misremembering but I thought that you had tried forcing the
pipe jobserver option on GNU/Hurd and it didn't help.

But, as you mentioned it's not widespread because it only affects

This is a long shot, but I had a problem a year ago with parallel make
on Cygwin occasionally hanging. The solution turned out to be to force
make's jobserver to use pipes instead of fifos. If you want to try
this, pass make the option '--jobserver-style=pipe'.
