Description Thomas Koenig 2019-05-05 08:10:39 UTC 
Came across this when looking at PR 90329. This is with recent trunk.

$ cat foo.f90
subroutine foo() BIND(C)
end subroutine foo
$ gfortran -c -fc-prototypes foo.f90
$ 

Probably looking at the wrong namespaces somewhere.

    * gfortran.dg/dump-parse-tree.c: Include version.h.
    (gfc_dump_external_c_prototypes): New function.
    (get_c_type_name): Select "char" as a name for a simple char.
    Adjust to handling external functions. Also handle complex.
    (write_decl): Add argument bind_c. Adjust for dumping of external
    procedures.
    (write_proc): Likewise.
    (write_interop_decl): Add bind_c argument to call of write_proc.
    * gfortran.h: Add prototype for gfc_dump_external_c_prototypes.
    * lang.opt: Add -fc-prototypes-external flag.
    * parse.c (gfc_parse_file): Move dumping of BIND(C) prototypes.
    Call gfc_dump_external_c_prototypes if option is set.
    * invoke.texi: Document -fc-prototypes-external.
