Compatibility of array indexing for gcc 3.4.6 and gcc 4.4.7?

[Stefan Schmitt]

Thank you all very much for your valuable comments.

As I said before, the problem is with getting backwards-compatible 
results from a very large piece of code (millions of lines of code), when 
going from the 32-bit to the 64-bit system.

I mentioned one of the problems in this forum and was asking for help.
Apparently there seems to be no easy solution. If course I can fix the 
specific problem by adding the line
      index=iand(index,z'3fffffff')
but there may be hundreds of similar problems hidden elsewhere. This is 
why I have been asking for a compatibility flag. Please apologize for 
having wasted your time, I am not going to come back again.
