Compiler flag to put all symbols in a namespace

[dru...@chromium.org]

I noticed third_party/unrar/src defines all of its symbols in the global namespace, which is not ideal. Is there an easy way to put all of these symbols into a namespace? I'm hoping for some sort of compiler flags/configuration, rather than just going through each file and adding a namespace declaration, since the latter makes it hard to pull in new versions of unrar.

We looked for ways to do things like this in order to make it easier to build more code in jumbo mode, and came up empty handed.  So I don't think there's a good way to do what you want.  

You could experiment with symbol renaming or prefixing with objcopy, but I think this would require that you maintain a separate header file with the mangled names for client code to use.  I have seen this used in some C libraries, but it makes debugging difficult, and I suspect this would be more difficult to do with C++ symbols.  I doubt this would work well.
