I don't think so (at least not directly) as
got me beyond that point.

then gets a floating point exception when calling
CALL ZBKNU(ZNR, ZNI, FNU, KODE, NN, CYR, CYI, NZ, TOL, ELIM, ALIM)
(whose code contains similarly
DBLE(FLOAT(I1MACH(14)-1)) - but I did not follow this further ...)
Integer at (^) too large

Though that ATLAS works fine with "old" scipy and the
corresponding debian packages. So I am not sure
what to do about it ...

That would be the nicest solution, I'd guess.

I will have to leave that for tomorrow (if I find
a way how to do this - at first glance it was not obvious to me ...)
