Reading the standard, any 'constant-expression' is valid for #if, and sizeof
is yielding a constant. So, one should be able to say:
#if sizeof (a) == 2
etc. I read it a while ago and though it too bad my compiler won't do this.
No separate cpp will do it (unless it learns some C).
Comments? I was reading 3.8.1 7/88 draft.
