re PR fortran/32579 (problem using iso_c_binding (II))
2007-07-02 Christopher D. Rickett <crickett@lanl.gov>
PR fortran/32579
* symbol.c (gen_cptr_param): Generate C_PTR and C_FUNPTR if
necessary.
(build_formal_args): Pass intrinsic module symbol id to
gen_cptr_param.
* gfortran.dg/iso_c_binding_only.f03: Updated test case.
