|> As far as I know, ISO C is not a standard yet.
ISO C *is* the current standard. There is no difference between ISO C and
ANSI C (except the latter being USA centric).
There is the C standard where the work was done in ANSI, which ISO then
blessed, and the new C standard which is currently being worked on
within an ISO working group.
Many people refer to the C standard where the work was done in ANSI as
"ANSI C", and the upcoming modifications to the C standard (which will
add explicitly bit-width sized types, among other things), as ISO C.
(Which is to say, the upcoming C standard which the ISO folks are
conspiring to inflict on the rest of world. :-)
