test version built and on the way
The problems I reported with make 4.4 still exist in 4.4.0.90.
Until someone can figure out why this happens, you might want to
consider building make so that it doesn't default to using a FIFO for
its jobserver. I suggested to the make developers that they provide
a configure option for this purpose. If they don't do this, I think
you could accomplish the same thing by configuring make with
ac_cv_func_mkfifo=no.

Thanks, Marco. As expected, that fixes the problem for my test case
(building TeX Live). Obviously it would be better if the make
developers would provide a configure option to use a pipe for the
jobserver, but this is a good workaround if they don't.
Just to finish this off, there's now a new release candidate 4.4.0.91
for make, which makes the jobserver use a pipe by default on Cygwin.
You can override this default when building make by defining
JOBSERVER_USE_FIFO to 1, and you can override it when running make by
using the make option --jobserver-style=fifo. But there's no longer a
need to build make with ac_cv_func_mkfifo=no, and there's no longer a
need to use --jobserver-style=pipe when running make.
I'm very impressed with how responsive the make developer (Paul Smith) was.
