well they should... especially since ansi says that library functions
(ahem, printf, strlen, etc), can be implemented as macros.  they *should*
behave like functions.

and now with C99 bringing about these {aggregate initilizers}, this
are bound to get broken, if you pass them around.

oh well, it seems no one is agreeing with me on this one.
