Well, other than suppressing the warning somehow.

I'm not sure I agree. I think if we can make it a function-like
macro, then it is fine to give it a function-like name. (Note that
many libc functions might be macros; getc is traditionally a #define.)
Obviously it can't be function-like in that you must always pass it a
literal, but violations of that constraint will be detected by the
compiler.
