This is a known problem with named fifos on Cygwin (see BUGS).  I have
a plan to fix it, basically by converting it to use `make -j` as the
source of parallelism, but that's a big change and I think it should
wait for 2.73.  I don't have access to a Cygwin environment; do you
have time to write a patch that makes "make check" skip these tests
on Cygwin?  The code to modify is AT_SKIP_PARALLEL_TESTS in
tests/autotest.at.

Thanks,
