-dnl Check for System V IPC calls used by Unix simulators

-dnl Note: $host_os should probably *not* ever be used here to
-dnl determine if host supports System V IPC calls, since some
-dnl (e.g. FreeBSD 2.x) are configured by default to include only
-dnl a subset of the System V IPC calls. Therefore, to make sure
-dnl all of the required calls are found, test for each call explicitly.
-dnl
-dnl All of the calls use IPC_PRIVATE, so tests will not unintentionally
-dnl modify any existing key sets. See the man pages for semget, shmget,
-dnl msgget, semctl, shmctl and msgctl for details.
