2007-01-11  Andreas Tobler  <a.tobler@schweiz.org>

	* configure.ac: Replaced HAS_I386_THREAD_STATE_* with
	HAS_X86_THREAD_STATE32_* and HAS_X86_THREAD_STATE64_* respectively.
	* configure: Regenerated.
	* include/private/gcconfig.h (DARWIN): Added X86_64 define for Darwin.
	Added base definitions for the X86_64 Darwin port.
	* include/private/gc_priv.h: Added definitions for Darwin MACH thread
	operations. Moved existing THREAD_STATE info from darwin_stop_world.c.
	* darwin_stop_world.c: Removed THREAD_STATE info. Added
	HAS_X86_THREAD_STATE64___RAX. And replaced HAS_I386_THREAD_STATE___EAX
	with HAS_X86_THREAD_STATE32___EAX.
	(GC_push_all_stacks): Use GC_MACH_THREAD_STATE_COUNT. Add code for
	X86_64 Darwin.
	* dyn_load.c (GC_dyld_name_for_hdr): Use GC_MACH_HEADER.
	(GC_dyld_image_add): Use GC_MACH_HEADER and GC_MACH_SECTION.
	Distinguish between getsectbynamefromheader_64 and
	getsectbynamefromheader.
	(GC_dyld_image_remove): Likewise.
	* os_dep.c (GC_dirty_init): Use GC_MACH_THREAD_STATE.
	(catch_exception_raise): Introduce exception information for I386 and
	X86_64 Darwin. Add X86_64 for exc_state.faultvaddr.
