# XXX
# When we started using "| $$$$(dir $$$$@)/." for directory deps, these
# rules started getting used when object splitting is enabled for some
# reason. But they fail with
#   **splitmangle**: openBinaryFile: does not exist (No such file or directory)
# so for now they're commented out. They aren't needed, as we can always
# go directly to .o files.
