[cfe-dev] A checker that checks macro calls

[eph]

Todd,

did you suceed with building a Checker for Macros and their arguments, and
if yes, can you share how you did it? I'm currently facing the same problem,
my code uses a lot of macro calls, and basing a checker on them is much
easier than trying to re-assemble them on a function call level, but I am a
bit lost in the clang API.

Many Thanks
Eph
