 // Some ideas:
 //
-// 1. Add options to disable any of the checks, in case
-// there is some problem with them, or the messages get too verbose.
+// 1. Check for and warn about "#include" directives inside 'extern "C/C++" {}'
+// and "namespace (name) {}" blocks.
 //
-// 2. Try to figure out the preprocessor conditional directives that
-// contribute to problems and tie them to the inconsistent definitions.
+// 2. Omit duplicate "not always provided" messages
 //
-// 3. Check for correct and consistent usage of extern "C" {} and other
-// directives. Warn about #include inside extern "C" {}.

+// there is some problem with them, or the messages get too verbose.
 //
-// 4. There seem to be a lot of spurious "not always provided" messages,
-// and many duplicates of these, which seem to occur when something is
-// defined within a preprocessor conditional block, even if the conditional
-// always evaluates the same in the stand-alone case.  Perhaps we could
-// collapse the duplicates, and add an option for disabling the test (see #4).

 // 5. There are some legitimate uses of preprocessor macros that
 // modularize will flag as errors, such as repeatedly #include'ing
