gcc/ChangeLog:

	* explow.c (set_stack_check_libfunc): Adjust to accept name as a
	string instead of SYMBOL_REF rtx.
	* rtl.h (set_stack_check_libfunc): Move prototype from here...
	* libfuncs.h: ...to here.  Adjust for explow.c change.

ada/ChangeLog:
	* gcc-interface/trans.c: Do not include rtl.h, insclude libfuncs.h.
	(gigi): Adjust call to set_stack_check_libfunc.
