adaint.h: (__gnat_plist_init): Not defined for RTX.

2007-12-06  Jose Ruiz  <ruiz@adacore.com>

	* adaint.h: (__gnat_plist_init): Not defined for RTX.

	* initialize.c (__gnat_initialize): Do not call __gnat_plist_init for
	RTX systems.

	* Makefile.in: Add new files s-tasinf-linux.ads and s-tasinf-linux.adb.
	(LIBGNAT_TARGET_PAIRS, MISCLIB, THREADSLIB,
	EXTRA_GNATRTL_NONTASKING_OBJS, EXTRA_GNATRTL_TASKING_OBJS,
	GNATLIB_SHARED for RTX run time): Use the versions required by RTX.

	* mingw32.h:
	Do not define GNAT_UNICODE_SUPPORT for RTX since it is not supported.

	* sysdep.c (winflush_function for RTX): Procedure that does nothing
	since we only have problems with Windows 95/98, which are not
	supported by RTX.
	(__gnat_ttyname): Return the empty string on Nucleus, just as
	done on vxworks.
