That's actually nonsense. The procedure name is "C_F_PROCPOINTER" (-proc- not
-FUN-). (It's C_FUNLOC and type(c_funptr) but c_f_procpointer). There is no
argument checking, but the library function called is
__iso_c_binding_c_f_procpointer_i4 ! note extra _i4.
(which does not exist). I don't see how one could get rid of the _<datatype>
and thus I maintain what I wrote before: It is not possible from gfortran to
access that procedure, except by calling "__iso_c_binding_c_f_procpointer".
