2008-05-20 Thomas Quinot <quinot@adacore.com>

	* Makefile.rtl (GNAT.Sockets.Thin_Common): New unit.

	* g-sttsne-vxworks.adb: Add missing dependency on Sockets.Constants.
	Add missing "with" of Ada.Unchecked_Conversion

	* g-soccon-linux-ppc.ads, g-soccon-linux-64.ads, g-soccon-lynxos.ads, 
	g-soccon-linux-x86.ads, g-soccon-hpux-ia64.ads, 
	g-soccon-solaris-64.ads, g-soccon-tru64.ads, g-soccon-aix.ads, 
	g-soccon-irix.ads, g-soccon-hpux.ads, g-soccon-solaris.ads, 
	g-soccon-vms.ads, g-soccon-mingw.ads, g-soccon-vxworks.ads, 
	g-socthi-vxworks.adb, g-soccon-freebsd.ads, g-soccon.ads: 
	Move common code out of GNAT.Sockets.Thin implementations and into
	Thin_Common.
	New constant SIZEOF_fd_set
	New flag Has_Sockaddr_Len
	New constants SIZEOF_sockaddr_in, SIZEOF_sockaddr_in6

	* g-stsifd-sockets.adb
	(Create): Remove call to Set_Length; use Set_Family to set the family
	and (on appropriate platforms) length fields in struct sockaddr.

	* g-socthi.adb, g-socthi.ads, g-socthi-vms.ads, g-socthi-vms.adb, 
	g-socthi-mingw.adb, g-socthi-mingw.ads, g-socthi-vxworks.adb, 
	g-soccon-darwin.ads, g-soccon-darwin.ads: New constant SIZEOF_fd_set
	Move common code out of GNAT.Sockets.Thin implementations and into
	Thin_Common.

	* g-socket.ads, g-socket.adb: 
	Move common code out of GNAT.Sockets.Thin implementations and into
	Thin_Common.
	(Connect_Socket, Accept_Socket): Provide new versions of these two
	routines that operate with a user specified timeout.
	(Bind_Socket, Connect_Socket, Send_Socket): Remove calls to Set_Length,
	this is now handled automatically by Set_Family on platforms that
	require it.

	* gen-soccon.c: 
	Move common code out of GNAT.Sockets.Thin implementations and into
	Thin_Common.
	(SIZEOF_sockaddr_in6): On platforms where IPv6 is not supported, define
	this constant to 0 (not -1) because we use it to initialize an
	unsigned_char value.
	Align values for numeric constants only.
	Handle the case of systems that do not support AF_INET6.
	New constant SIZEOF_fd_set
	New flag Has_Sockaddr_Len
	New constants SIZEOF_sockaddr_in, SIZEOF_sockaddr_in6

	* gsocket.h: New flag Has_Sockaddr_Len
	New constants SIZEOF_sockaddr_in, SIZEOF_sockaddr_in6
