I would advice AVOID C macros at all cost. They are so weak and hard to debug and problematic.
I write in several languages and read lots of C projects made by others and find the affirmation hard to believe: C is so simple that is very easy to read if the writer of code has a minimum of competency.
You can say that of projects like C++, specially things like C++11 that are languages by committee so complex that you can affirm that every C++ programmer is different or find programmers that could not understand each coder's code. Not so with C.
That happens to me with C++ and lisp code. It takes a while for me to understand what the author uses(or abuses) before being able to understand the code. That does not happen with C code.
