Details:

If you try to compile an Objective-C++ module with gcc 4.6, you get this
error:

In file included from
/home/lcampbel/dev/gnustep-base-1.24.0/akamai/common/GNUstep/Local/Library/Headers/Foundation/Foundation.h:68:0,

error: 'NSDirectoryEnumerator' has a field 'NSDirectoryEnumerator::_flags'
whose type uses the anonymous namespace [-Werror]
cc1objplus: all warnings being treated as errors

Adding a tag to the 'struct { ... } _flags;' ivar fixes this:
