+# XXX: Associated variable aliasing:
+#
+# Some parameters bind to different variables in different contexts,
+# And other parameters map to associated variables in a many-to-1
+# fashion. This is mostly the result of the SMTP+LMTP integration
+# and the overloading of parameters that have identical semantics,
+# for the corresponding context.
+#
+# The "++table[...]" below ignores the associated variable name
+# when doing duplicate elimination. Differences in the default value
+# or lower/upper bounds still result in "postconf -d" duplicates,
+# which are a sign of an error somewhere...
+#
+# XXX Work around ancient AWK implementations with a 10 file limit
+# and no working close() operator (e.g. Solaris). Some systems
+# have a more modern implementation that is XPG4-compatible, but it
+# is too much bother to find out where each system keeps these.
