LEN Now An Intrinsic Function on Crays

Many Cray Fortran user codes are declaring LEN to be external, but since it is an intrinsic, the loader cannnot find a LEN() in the libraries.

This happened as a result of the last compiler/loader upgrade on the Crays.

The fix, of course, is to remove the statement:

	EXTERNAL LEN

from the code. This allows the compiler to use the intrinsic function.
