adaint.c (__gnat_get_libraries_from_registry): Call explicitly the ASCII version of the registry API.

2006-10-31  Pascal Obry  <obry@adacore.com>
	    Eric Botcazou  <ebotcazou@adacore.com>
	    Vincent Celier  <celier@adacore.com>

	* adaint.c (__gnat_get_libraries_from_registry): Call explicitly the
	ASCII version of the registry API. This is needed as the GNAT runtime
	is now UNICODE by default.
	Include version.h.
	(get_gcc_version): Do not hardcode the return value.
	(__gnat_file_time_name): On Windows properly set the default returned
	value to -1 which corresponds to Invalid_Time.
	(__gnat_fopen): New routine. A simple wrapper on all plateforms
	 except on Windows where it does conversion for unicode support.
	(__gnat_freopen): Idem.
	(__gnat_locate_exec_on_path): If environment variable PATH does not
	exist, return a NULL pointer

	* adaint.h: (__gnat_fopen): Declare.
	(__gnat_freopen): Likewise.

	* mingw32.h (_tfreopen): Define this macro here for older MingW
	version.
	Activate the unicode support on platforms using a MingW runtime
	version 3.9 or newer.

	* s-crtl.ads (fopen): Is now an import to the wrapper __gnat_freopen.
	This is needed for proper unicode support on Windows.
	(freopen): Idem.
