Bug in the objective-c++ compiler?

Hi!

For the following simple C++ code (nothing else) and using Xcode 2.1 with gcc4:

namespace Toto {
    enum Protocol {eOther};
    Protocol getProtocol(void) {return eOther;}
}

Can anyone tell me why I'm getting the following error message with the objective-c++ compiler:

main.mm:3: error: 'Toto::Protocol' referred to as 'struct'
main.mm:2: error: 'Toto::Protocol' has a previous declaration here

It appears as if there is a predefined "struct Protocol" in objective- c, and that the objective-c++ compiler is confusing it with Toto::Protocol wich is an enum type.

If I replace the word "Protocol" by anything else, the error message disappears. Also, if I compile with gcc3.3 instead of gcc4, there is not problem.

Is "Protocol" a new reserved keyword in objective-c?

Many thanks in advance,
