is terminated by a signal, rather than a normal exit, the result is the
signal number shifted left by eight bits.
address@hidden This test has difficulties being portable, even on platforms
address@hidden where syscmd invokes /bin/sh. Kill is not portable with signal
address@hidden names. According to autoconf, the only portable signal numbers
address@hidden are 1 (HUP), 2 (INT), 9 (KILL), 13 (PIPE) and 15 (TERM). But
address@hidden all shells handle SIGINT, and ksh handles HUP (as in, the shell
address@hidden exits normally rather than letting the signal terminate it).
address@hidden Also, TERM is flaky, as it can also kill the running m4 on
address@hidden systems where /bin/sh does not create its own process group.
address@hidden That leaves KILL and PIPE as the two signals tested.
@example
dnl This test assumes kill is a shell builtin, and that signals are
dnl recognizable.
