The Cray 7.1 compiler (the current release) implements everything except 
the ISO characters, which are optional (and for which we've seen zero 
interest so far). So, we claim full conformance with f03.  The automatic 
array reallocation on assignment feature is enabled with a compiler 
flag, to avoid the performance hit on unsuspecting users.  The 
submodules TR is also included in the 7.1 compiler.

Cheers,
Bill
