+
+# MachTen 4.0.2 and earlier do not implement System V interprocess
+# communication (message queues, semaphores and shered memory); 4.0.3 has a
+# half-baked implementation which provides the corresponding library
+# functions but does not implement the system calls or provide the header
+# files (or documentation).  The perl installation process correctly divines
+# that System V IPC is not usable in either case.  Do not attempt to persuade
+# it otherwise, or the resulting perl will crash (rather than producing an
+# error message) if you attempt to use the functions.
