[mpich2-dev] Fw: 32-bit ROMIO: What is the best solution?

[William Gropp]

Any place where sizeof(int*) == sizeof(int) is assumed is just broken  
- if its easy to separate those out, we'll just apply a fix for  
those, since that's needed for any platform and under all  
conditions.  The sizeof(MPI_Aint) == sizeof(void*) assumption will  
require more care.
