No, only that I remember seeing a discussion about it, most likely on
comp.std.c so most likely not about POSIX, and before C11. I can't
find any trace in my own archives, and asking the goog about
comp.std.c turns up tons of rubbish about comp.std.c++, and I don't
see anything obvious in the standard either.
But of course it would only be an interesting proposition for
comp.std.c if it weren't obvious :-)
Could also be that I'm thinking of something else entirely. So, in the
absence of further information, never mind I guess...
