C++11: Compiler errors in auto-generated slice code

I'm upgrading my C++ Ice project to use C++11, but I'm running in to problems with the auto-generated slice code.

I'm using g++ (Ubuntu/Linaro 4.7.3-2ubuntu4) 4.7.3. If I compile without '-std=c++11', everything compiles fine.

As far as I can tell, the ::Ice::Context parameter isn't getting named properly. In the non-C++11 code, a function definition has the following arguments -- ::Ice::Int ctx, const ::Ice::Context& __ctx -- but in the C++11 case it looks like this (notice the missing __): ::Ice::Int ctx, const ::Ice::Context& ctx

Here's what the compiler spits back:

    Hi,

    This is a known issue that will be fixed with Ice 3.5.1. In the meantime, you can rename the "int ctx" parameter of the addContextCallback method in the Murmur.ice slice file (to "int cbCtx" for example). This should workaround the problem.

    Cheers,
    Benoit.

    Yep, that's what I did. Just wanted to make sure you guys were aware of the issue as well. :)
