+
+ portability: fix several issues with M4 subprocess.
+
+ 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

+ 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.
