Denny + + portability: fix several issues with M4 subprocess. + + M4's output pipe was not being drained upon fatal errors during + scan_skel.

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.
