+// FIXME: seems like cocci has problems manipulating the declarations, at least
+// when there is more than one on the same line. We already need perl to split
+// up the declarations after the fact, is there another tool we can use to patch
+// up and match the declarations? In that case we could consider dropping cocci,
+// or just using it to alter global variable accesses.
+//
 // FIXME: problems
-//   - does not want to match dynamic arrays...
+//   - array declarations not properly matched...can fix, but then can't have
+//   multiple declarations on one line
 //   - does not match array initializers
+//   - probably won't fix structure declarations with initialization either
 
 // Function prototype looks like variable dec, but has parentheses
