# Attempt to declare a generator for creating OBJ from RC files. That generator
# should be considered together with standard CPP->OBJ generators and
# successfully create the target. Since we do not have a RC compiler everywhere,
# we fake the action. The resulting OBJ will be unusable, but it must be
# created.
