Is the problem with i1mach? 

You could replace the line with

BB=DBLE(2147483647)*0.5D0

or

BB=DBLE(FLOAT(21477483647))*0.5D0

and see if that helps.


The other problems may be ATLAS issues.  Yes, it could be compiler 
optimization problems.  Presumably distutils has a way to turn off 
compiler optimizations.  You could compile the amos library manually 
without compiler optimizations and just place it in the build/tempYYYYY/ 
directory where it will be picked up by distutils.
