C++ Parser and gcc internal defines

[Jonathan Schmidt-Dominé - Developer]

Hi!

I think KDevelop does not know about all these flags.
But if you would create a list (it can be incomplete ;)) of such flags, it 
should not be too complicate to handle that in the cmake-support and we could 
easily fix it. It would be enough to pass the definitions to kdev's 
preprocessor if the flag occurs in cmake's add_definitions?
