[Rd] Assistance much appreciated

[Simon Urbanek]

Michael,

I got access to PDP AIX so I can try to replicate your problem. Can you, please, share exactly your setup - AIX version and well as how exactly you installed the compilers (=where from)? I can then try to replicate it. AFAICS there is no official binary for gfortran nor gcc 4.7 so it must be some 3rd party - which could also be a problem.

Thanks,
Simon
