--- Comment #2 from Rainer Orth <ro at gcc dot gnu.org> ---
The attached patch makes all but a single failure go away:

FAIL: gfortran.dg/assumed_charlen_function_7.f90   -O  (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gfortran.dg/assumed_charlen_function_7.f90:18:4:
Warning: Obsolescent feature: CHARACTER(*) function 'abc_interface' at (1)
