i know, but neither will any standard library functions that are 
implemented as macros.  take a pick: a little flexibility on macro
arguments, or inability to pass constant aggregates to library functions 
(that have been implemented as macros).  you can't have both.

of course, this wouldn't be implemented for -ansi.

but they're not part of the ISO C standard :-(
