$$ is special in make, it resolves to $ which is useful for secondary expansion of variables.
You can do $${foo} and its not until the make file that it looks for ${foo}. Useful for most but not used in CMake.
Making it $$$$ fixes this, the problem being we need an item that can't be used in PHP class names to avoid collisions.
I've reported this to the CMake people and I'm working on a workaround for now.

Fixed now by changing our generator to use ____, I've reported the bug to CMake though.

This issue appears to be back I think it might have been changed back to $$ in src/compiler/option.cpp:84 and it's still not fixed in Cmake. I ran into it compiling wordpress 3.4

Looks like it was changed with b386ff0 not sure what the best fix is. Perhaps just patch cmake?
