    _______________________________________________________

Details:

The test for the fallthrough attribute fails due to other compiler
warnings when using clang.  The following warnings are generated:

   warning: no case matching constant switch condition '0'
   warning: control reaches end of non-void function [-Wreturn-type]

Because of these additional warnings, the test always results in a
failure for the fallthrough attribute.

Attached is the patch that I submitted as a pull request on github (

Thank you
