Well I'll ask them and then I'll know. ;)
But that would technically be the correct point, and seems
to be the policy of glibc.

: This is of course not very helpful.  I would suggest you try 
: -ansi -D_XOPEN_SOURCE=500; that gets you a conforming-mode compiler,
: and (I think) all of the C library except the GNU extensions.

Yes. In fact, I just using the C99 switch will work for me.
However, once you know that you already know the problem.

On a larger scope, I wouldn't like to see others spend a
significant amount of time finding out about that (common)
mistake.
