* fortran/trans-array.c (gfc_conv_resolve_dependencies): Add string
length to temp_ss for character pointer array assignments.
* fortran/trans-expr.c (gfc_conv_variable): Correct errors in
dereferencing of characters and character pointers.
* fortran/trans-expr.c (gfc_conv_function_call): Provide string
length as return argument for various kinds of handling of return.
Return a char[]* temporary for character pointer functions and
dereference the temporary upon return.
