Testcase:
function f()
REAL :: f
f = 1.0
end function
call f
end
-----
This is very much related to PR 23308.
The problem here is the main issue why we create two decls for f in the
following program:
function f()
REAL :: f
f = 1.0
end function
g = f()
end

symbol in the encompassing namespace, call errors
if it is a procedure of the same name or the kind
field is set, indicating a type declaration.

* decl.c (add_global_entry): New function to check
for existing global symbol with this name and to
create new one if none exists.
(gfc_match_entry): Call add_global_entry before
matching argument lists for subroutine and function
entries.
* gfortran.h: Prototype for existing function,
global_used.
* resolve.c (resolve_global_procedure): New function
to check global symbols for procedures.
(resolve_call, resolve_function): Calls to this
new function for non-contained and non-module
procedures.
* match.c (match_common): Add check for existing
global symbol, creat one if none exists and emit
error if there is a clash.
* parse.c (global_used): Remove static and use the
gsymbol name rather than the new_block name, so that
the function can be called from resolve.c.
(parse_block_data, parse_module, add_global_procedure):
Improve checks for existing gsymbols. Emit error if
already defined or if references were to another type.
Set defined flag.
PR fortran/PR24276
* trans-expr.c (gfc_conv_aliased_arg): New function called by
gfc_conv_function_call that coverts an expression for an aliased
component reference to a derived type array into a temporary array
of the same type as the component. The temporary is passed as an
actual argument for the procedure call and is copied back to the
derived type after the call.
(is_aliased_array): New function that detects an array reference
that is followed by a component reference.
(gfc_conv_function_call): Detect an aliased actual argument with
is_aliased_array and convert it to a temporary and back again
using gfc_conv_aliased_arg.

that is not a dummy argument.

Fixed on trunk and 4.1

Andrew, I have not forgotten the type checking - I am working on it for
internal procedures first; gfortran might be OK but the standard is quite
convoluted here and I have not got it completely straight in my head.... yet.
