Ah-hah.  This probably indicates that the gcc you are using was
originally generated on a different version of AIX.  It's always bad
news when gcc's copies of the headers don't match the real ones :-(

These copies are generated during gcc build by a script called
"fixincludes".  You might be able to fix them up by just re-running
fixincludes.  My inclination would be to rebuild gcc altogether though.
