+        For formatted input/output, if the explicit widths after the data-edit
+        descriptors <code>I</code>, <code>F</code> and <code>G</code> have been

+      <li>
+        A blank format item at the end of a format specification, i.e. nothing
+        following the final comma, is allowed.  Use the option
+        <code>-fdec-blank-format-item</code>, this options is implied with

+        <code>AUTOMATIC</code> attribute to be used in <code>EQUIVALENCE</code>
+        statements. Use <code>-fdec-static</code>, this option is implied by
+        <code>-fdec</code>.

+        <code>COMPLEX</code>) or <code>LOGICAL</code> variables.  Use the option

+      <li>
+        DEC comparisons, i.e. allow Hollerith constants to be used in comparisons
+        with <code>INTEGER</code>, <code>REAL</code>, <code>COMPLEX</code> and

+    <li>
+      Character type names in errors and warnings now include <code>len</code>
+      in addition to <code>kind</code>; <code>*</code> is used for assumed
