This should be the -qlanglvl option:

E.g.

xlc -qlanglvl=stdc99

and for C++ probably:

xlC -qlanglvl=c99__func__

>From the man page:
  stdc89
    Compilation conforms to the ANSI C89 standard,
    also known as ISO C90.
  stdc99
    Compilation conforms to the ISO C99 standard.

This is for v7.0. I don't know how older versions of xlc would handle this
and or whether IBM being IBM would change things in later compiler versions.

All the best
Ross
