Same.

seems like a compiler bug

i changed /System/Library/Frameworks/CoreGraphics.framework/Headers/CGBase.h:16 from

# define __CG_HAS_COMPILER_ATTRIBUTE(attribute) __has_attribute(attribute)

to

# define __CG_HAS_COMPILER_ATTRIBUTE __has_attribute

and it worked for me

Tested on Yosemite

Rather than modify Apple's CoreGraphics framework, I instead was able to prepend ruby/ruby.cpp:
#define __has_attribute(x) 0 // Compatibility with non-clang compilers.

Furthermore, in my experience building higan v094 for OSX, other modifications were necessary. I am including a patch:

Patch Notes

• The Makefile changes are purely personal but remain included.
• The shader modification was made because higan would crash on startup. This fix seems to be doing alright, and shader presets do still load up on startup :) -- the problem stems from the call to glGenTextures ruby/video/opengel/main.hpp:54 which arises from lack of OpenGL context.
• The addition to carbon.cpp is completely necessary and it seems Byuu and company forgot about testing on Apple since this function's existence is basically crucial
• In my case, the makefile for shader installation on OSX is incorrect. they should be installed in /Library/Application Support/higan/Video Shaders but they are incorrectly installed into /usr/share/higan/Video Shaders
