[Jacob Kroon]

References to undefined variables are preserved as is and do not
expand to nothing as in GNU Make.

                 The ":=" operator results in a variable's
                 contents being expanded immediately,
-                rather than when the variable is actually used:
-                <literallayout class='monospaced'>
-     T = "123"
-     A := "${B} ${A} test ${T}"
-     T = "456"
-     B = "${T} bval"
-     C = "cval"
-     C := "${C}append"
-                </literallayout>
-                In this example, <filename>A</filename> contains
-                "test 123" because <filename>${B}</filename> and
-                <filename>${A}</filename> at the time of parsing are undefined,
-                which leaves "test 123".
-                And, the variable <filename>C</filename>
-                contains "cvalappend" since <filename>${C}</filename> immediately
-                expands to "cval".

+                references to undefined variables are preserved as is,
+                instead of evaluating to nothing.
