And failure on this test is already known to be a cygwin1.dll deficiency,
by both the autoconf team and by cgf (who has made progress on improving
pipes for 1.7, but is certainly facing a tough nut to crack).
Fortunately, the workaround is simple (albeit a bit more time-consuming) -
for testsuites created by autoconf, don't try running them in parallel on
cygwin (at least bison, tar, and m4 create testsuites via autoconf) until
pipe handling is improved.
Don't work too hard, make some time for fun as well!
