+# Tests for the special source .IGNORE in dependency declarations,
+# which ignores any command failures for that target.

+# Even though ignore-errors fails, the all target is still made.
+# Since the all target is not marked with .IGNORE, it stops at the
+# first failing command.

-# Tests for the special source .IGNORE in dependency declarations.
+# XXX: The messages in the output are confusing.
+# The "ignored" comes much too late to be related to the "false
+# ignore-errors".
+# The "continuing" is confusing as well since it doesn't answer the
+# question "continuing with what?".
+#
+# Even more interestingly, enabling the debugging option -de changes
+# the order in which the messages appear.  Now the "ignored" message
+# is issued in the correct position.  The manual page even defines the
+# buffering of debug_file and stdout, so there should be no variance.
