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

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.
Could you elaborate? I don't know what issue you're seeing.
There have been reports from various projects mentioning problems in
other packages ending up at make 4.4 and FIFOs solved by reverting to
pipes.
There is a make 4.4.1 release candidate 4.40.0.90 with patches that may
help to deal with this:
