--- Comment #3 from Steve Kargl <kargl at gcc dot gnu.org> ---
Suppressing the error by commenting out the code should
allow gfortran to continue to the resolution phase.  I get

% gfcx -o z p9.f90
p9.f90:4:2:

    4 |   character(1) function character_stop_code()
      |  1
Error: INTERNAL-PROC procedure at (1) is already declared as EXTERNAL-PROC
procedure

which is rather unexpected.
