It may be important to also emphasize that I am not proposing changing 
that. One can still write a Fortran wrapper that has
"type(*),dimension(*)"
and call C routines that have "void*". If you only want to pass an 
address around it will work great. You have an "ignore type and kind" 
directive.

The only issue here is what happens when descriptors are brought in the 
mix. That is, the real issue is the "ignore rank" thing, which is now 
intermingled with the type because the descriptor contains TKR 
information, not just TK or just R.
