M4's output pipe was not being drained upon fatal errors during
scan_skel. As a result, broken-pipe messages from M4 were seen
on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
failure in the test suite. The problem was that, on platforms
where the default disposition for SIGPIPE is ignore instead of
terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
then reported it. However, there's some sort of race condition,
because the new test group occasionally succeeded.
Reported by Albert Chin at
<http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
There were also problems with the test suite livelocking on
Tru64 5.1b. Reported by Didier Godefroy at
<http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
Switching to create_pipe_bidi suggested by Akim Demaille.
To attempt to solve both of these problems, switch to gnulib's
create_pipe_bidi and register M4 process as a slave. Along the
way, clean up file name conflict handling, which was affected by
the broken-pipe problem before the switch.
