Ok it does compile with -mno-ms-bitfields. But still causes a segfault without the gcc_struct patch (for me anyway). I think the problem is that other programs pick up and use for instance ifo_types.h (as a dependency) but then *they* don't add a -mno-ms-bitfields (perhaps they don't even want to? ) to their compilation so it still breaks when it ends up being used for method parameters, etc. If this is the problem, then I suppose possible fixes would be to just put a "gcc_struct" into the source code, or to export the -mno-ms-bitfields to the .pc file? I'm just guessing here I don't know for certain.
