Are we talking ISO C or GNU C here? This is OK for GNU C, and I think for POSIX.
You mentioned ISO C a few times. So i'd guess we are talking c89.

Because i happen to compile with 5-6 versions of gcc on different platforms with different ideas of what -W[xxx] turns on and throwing
`-pedantic' into the mix generally turns on more. [..snip..]

That's not for me to decide, not a language layer by any stretch of imagination. -- vale
