  • aclocal/check-posix.m4: Add m4-quotes. Require RTEMS_CANONICAL_TARGET_CPU instead of RTEMS_CHECK_CPU.
  • aclocal/canonical-host.m4: Remove.
  • configure.ac: Remove RTEMS_CANONICAL_HOST.
  • aclocal/sysv-ipc.m4: Remove reference to RTEMS_CANONICAL_HOST.
  • aclocal/canonical-target-name.m4: Use AC_CANONICAL_HOST instead of AC_CANONICAL_TARGET. Use $host instead of $target.
  • Property mode set to 100644
