+# -------------------------
+# Make sure that prefix characters apply properly to define/endef values.
+#
+# There's a bit of oddness here if you try to use a variable to hold the
+# prefix character for a define.  Even though something like this:
+#
+#       define foo
+#       echo bar
+#       endef
+#
+#       all: ; $(V)$(foo)
+#
+# (where V=@) can be seen by the user to be obviously different than this:
+#
+#       define foo
+#       $(V)echo bar
+#       endef
+#
+#       all: ; $(foo)
+#
+# and the user thinks it should behave the same as when the "@" is literal
+# instead of in a variable, that can't happen because by the time make
+# expands the variables for the command line and sees it begins with a "@" it
+# can't know anymore whether the prefix character came before the variable
+# reference or was included in the first line of the variable reference.
