Robert,

Thank you for the reference,  however I cannot find anywhere a
statement to the effect that these two flags should not be used
together.  In fact on page 18 the reader is refered to C
and C++ Application Development on AIX which clearly states on page
83 that these options can and should be used together.  I'm sure that
you realize that if things had been working correctly I would not have
felt the urge to send you a patch.  

Thank You,
Jim
