+    Your choices for getting past this for now are
+
+     - try and remove any single apostrophes in Fortran comments
+
+     - use gmake twice and live with possibly bad dependency information
+       for these files
+
+     - if you are using Linux, try using the option "-traditional" 
+       with the GNU cpp which does ignore the apostrophes.
