Emulator

What's the problem? Describe what went wrong in few words.

What did you expect to happen instead?

Compiling 4.0-6592 from source broke...

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. Tried to compiled 4.0-6592 from source but fails.

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

The last version I compiled works fine; 4.0.6337

Slackware 14.1 x86_64
gcc 4.8.2

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

PLEASE tell me I don't need GCC 4.9 now to compile dolphin?
