A PURE function that is part of an INTERFACE block is not resolved as being a
function. Gfortran gives the following warning for the code attached at the end
of this description:
module_procedure-1.f90: In function 'show':
module_procedure-1.f90:30: warning: unused variable 'test'
I originally tested this using GNU Fortran 95 (GCC 4.1.0 20050602
(experimental)) and retested it using GNU Fortran 95 (GCC 4.1.0 20050608
(experimental)).

------- Additional Comments From fxcoudert at gcc dot gnu dot org 2005-06-18 18:42 -------
Confirmed, we should not issue such warning. Here is a (slightly) reduced testcase:
MODULE procedures
PUBLIC :: test
PRIVATE :: test2
INTERFACE test
MODULE PROCEDURE test2
END INTERFACE test
CONTAINS
PURE INTEGER FUNCTION test2 ()
test2 = 0
END FUNCTION test2
END MODULE procedures
MODULE actions
USE procedures
CONTAINS
SUBROUTINE show
print *, test ()
END SUBROUTINE show
END MODULE actions
PROGRAM module_procedure_1
USE actions
CALL show
END PROGRAM module_procedure_1
