+# Q: Does Configure *really* get *all* of these wrong?
 #
+# A: Yes.  There are two MPE problems here.  The 'undef' functions exist on MPE,
+# but are merely dummy routines that return ENOTIMPL or ESYSERR.  Since they're
+# useless, let's just tell Perl to avoid them.  Also, a few data items are
+# 'undef' because while they may exist in structures, they are uninitialized.
+#
+# The 'define' cases are a bit weirder.  MPE has a libc.a, libc.sl, and two
+# special kernel shared libraries, /SYS/PUB/XL and /SYS/PUB/NL.  Much of what
+# is in libc.a is duplicated within XL and NL, so when we created libc.sl, we
+# omitted the duplicated functions.  Since Configure end ups scanning libc.sl,
+# we need to 'define' the functions that had been removed.
+#
+# We don't want to scan XL or NL because we would find way too many POSIX or
+# Unix named functions that are really vanilla MPE functions that do something
+# completely different than on POSIX or Unix.
