Denny + + 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.

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.

Use the /dev/null solution + for the case of two conflicting output files as well because it + seems safer in case Bison one day tries to open both files at + the same time. + * src/files.h (output_file_name_check): Update prototype. + * src/output.c (output_skeleton): Use create_pipe_bidi and + wait_subprocess.
