Added warning on structures/unions that are empty or contain only
...
bit fields of zero size. Warnings are generated in C++ mode and if
only such type is defined inside extern "C" block.
The patch fixed PR5065.

Add missing diagnostic for a nested-name-specifier on a free-standing type definition. Bump some related diagnostics from warning to extension in C++, since they're errors there. Add some missing checks for function specifiers on non-function declarations.

Don't warn about the 'extern' in 'extern "C"' on a tag decl. This is

When checking whether to diagnose an initialized "extern" variable,
...
look for the const on the base type rather than on the top-level
type. Fixes PR6495 properly.

Disable the "'extern' variable has an initializer" warning in C++,
