this is either a bug in the unix headers of AIX or gcc-4.0.0
and _not_ a Q-E problem.
most likely a combination of both. gcc-4.0.0 is a quite broken 
and long obsolete compiler version (it is a double zero release
and that almost always spells trouble).
i would recommend to either install a current gcc or use 
the system xlc (cc) instead.
sometimes header conflicts on AIX can be resolved by adding
-D__ALL_SOURCE to DFLAGS in make.sys
cheers,
   axel.
