There should also be a -pedantic-errors test that these constructs get 
errors with -pedantic-errors.

The tests mix two cases: flexible arrays in unions, and flexible arrays on 
their own in structures.  That means the test names are misleading; either 
they should be renamed, or the struct tests should be split out.

Note that "no named members" also includes the case where there are 
unnamed bit-fields together with a flexible array member, so that should 
be tested as well.

Since this patch series involves changes for both C and C++, it would be 
best for the tests to be c-c++-common tests.  But if that's problematic 
for some reason - if there's still too much difference in behavior between 
C and C++ - then there should at least be tests for C++ that are as 
similar as possible to the tests for C.
