[PATCH] AIX fixincludes for complex.h

[David Edelsohn]

The complex.h head in AIX refers to a feature for imaginary numbers
that is provided by XLC without protecting the usage.  This was
exposed with a recent change to libgfortran c99_functions.c.  I have
opened an AIX defect, but also need to fix this for current systems
using fixincludes.

I cannot fully run autogen on AIX.  I generated the new fixincl.x on a
Linux system, copied it to AIX and it correctly patches the file.  I
am not sure how to update the base files given the autogen limitations
of AIX.

Bootstrapped on powerpc-ibm-aix5.3.0.0.

Okay?

Thanks, David



        * inclhack.def (aix_complex): New fix.
        * fixincl.x: Regenerate.
