It occurs to me that you'll want a changelog entry when you do:

2006-09-30  Brooks Moses  <bmoses@stanford.edu>

	* invoke.texi:  Add mention of BOZ constants and integer
           overflow to -fno-range-check.
         * gfortran.texi:  Add mention of -fno-range-check to
           section on BOZ contants.

- Brooks
