# Check that we properly handle changing rule definitions where intermediate

#
# Second build where 'a.i' exists and is the same as before, but is no longer
# produced by anything in the manifest (i.e. is now a plain file node). This
# should be a null incremental build, as the input is still up to date. As such
# this will implicitly drop the dependency on C.1.

# Third build where the rule to produce 'a.h' has been added back. In this case
# it is still up to date, so we expect the build to continue to be null.
# However, we do expect that the build system scans rule C.1.
