Well, sure, but I find that particular fact singularly unimportant (no
offense intended).

If your intention is to write portable code, and you don't find the
prospect of source code littered with #ifdef's, the inclusion of something
into a language standard is *definitely* good news since the standard will
require it in compilers which purport to adhere to it.

IMHO, this is long overdue with respect to the C formatting functions.
