I am for easy, and having to specify this is difficult for cmake developers and
for cmake users.   The only thing cmake is parsing the files for is to create
depend information, that is it.   I have not yet seen a case where the cC*dD starting a
line would cause incorrect depend information and still be valid fortran code.
