I've removed Paul Thomas' backport (listed below) from the 4.1 branch
due to a regression reported here:

http://gcc.gnu.org/ml/fortran/2006-12/msg00192.html

The removal was accomplished by

svn merge -r 119694:119693
svn revert gcc/testsuite/ChangeLog
svn revert gcc/fortran/ChangeLog  
< Bootstrap and regression tested on x86_64-*-freebsd. >
svn commit .

        * resolve.c (resolve_symbol): Allow host-associated variables
        in the specification expression of an array-valued function.
