Subject: Re:  testsuite ISO_C_BIND code error

FPTR finally should POINT at that string (same thing CSTR points at)  
with the correct type info/structure/array-shape set up correctly.

My primary reason to send this in is that these test code provides  
great source code examples to figure out how this stuff SHOULD  
work...  in this case, I found myself taking on the role of debugger  
when I wasn't quite sure how it was supposed to work in the first  
place.  I just figured it would help out...
