- * g-socket.adb: A target can have multiple missing errno's. This
- will result in multiple errno's being defined as -1. Because of this
- we can not use a case but must use a series of if's to avoid
- a duplicate case error in GNAT.Sockets.Resolve_Error.

-
- * gcc-interface/trans.c (call_to_gnu): Open a nesting level if this is

- for CONSTRUCTORs.
- For a function call, emit the range check if necessary.
- In the copy-in copy-out case, create the temporary for the return
- value explicitly.
- Do not unnecessarily convert by-ref parameters to the formal's type.
- Remove obsolete guards in conditions.

- target to call_to_gnu in all cases.
