What do you do about user code that #undef's func? That is valid for a
number of macro/function pairs (e.g. fgetc). What do you do about user
defined structs with a field "func"? That's perfectly valid C and would
break horrible depending on the include order of header files.

In short, there is *no* standard way to achieve this behaviour.
