Please do not do like this. Excluding specific platform is acceptable only why
you understand why the failure happens -- what is the actual reason?  Does it
because of fontconfig?  Does it because of specific font settings?
Also, please do not assign TODO like this to someone else. That's your failure,
you should fix this.

Why not just #if defined(OS_MACOSX) ?
