    a macro will be expanded into C code and is not a direct function call so you cant do that

    You mean something like
    gcc -DTABLE_SIZE=100 prog.c
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
