[cfe-dev] Check if inside a header file

[Nikola Smiljanic]

I was actually looking at this
http://llvm.org/bugs/show_bug.cgi?id=16686but it seems that there's no
way to fix this. I understand that compiler
doesn't care, but I was hoping that this information was stored somewhere
(at least based on file extension). Any other ideas?
