    Actually, *all* compilers do sizeof("constant") at compile time.
    Unfortunately, many also declare storage for the string even though it
    is never referenced.  That has always amused me.

    Perhaps you were talking about strlen("constant"); ??  This whole
    argument is over builtins and compiler optimization of said.
