omake is a ClearCase make tool and the -EN switch is meant to make it behave like nmake.
If, as the OP states, the dates on the dependancy files are really not later than that of the target then it shouldn't be trying to rebuild the Makefile. But if the make tool doesn't know how to handle dependancies it would be pretty useless and ClearCase is a big enough name to consider that unlikely.
