Thanks for this observation.  I will modify ufuncobject.h as you suggested,
instead.  The other problem still results in a complaint, but not an error;
it does not prevent compilation.

I have another little problem but I expect to be able to solve it.  I will
report when and if I have Numpy installed.

I suspect this allowed compilation, but I'm not sure if it "solved the
problem."  It depends on whether or not the FE_OVERFLOW defined in
fenv.h is the same as FP_OVERFLOW on the _AIX (it might be...).  The
better solution is to change the constant to what it should be...

Did the long double *,  double * problem also resolve itself?  This
seems to an error with the modfl function you are picking up since the
AIX docs say that modfl should take and receive long double arguments.

Best,
