* gcc-interface/Makefile.in (LIBGNAT_TARGET_PAIRS [windows targets]):

	Correctly detect cygwin, which no longer has the '32' suffix, and use
	appropriate implementations of the sockets and memory packages.
	* sysdep.c (WIN_SETMODE): New define to choose the correct spelling of
	setmode/_setmode for MinGW and Cygwin, respectively.
	(__gnat_set_binary_mode [windows targets]): Use the above, and enable
	the windows version for Cygwin as well as MinGW.
	(__gnat_set_text_mode [windows targets]): Likewise.
	(__gnat_ttyname [windows targets]): Provide a Cygwin implementation
	in addition to the MinGW version.
	(__gnat_is_windows_xp): Make available to Cygwin as well as MinGW.
	(__gnat_get_stack_bounds): Likewise.
