There are 3 commits to gcc/fortran in that range.  I
reverted what would be the obvious one that might
cause a problem and the ICE still occurs.

The ICE disappears if uppercase_c and uppercase_s are
moved up in the source code to a location that comes
before any reference to the generic uppercase.
