storage leaks.
	(breakpoint_re_set_one):  Fix b->exp, b->val, b->cond storage leaks.

	* infcmd.c (run_command), solib.c (locate_base):  Check for
	target_has_execution in addition to inferior_pid, a core file
	from a threaded program is yielding a non-zero inferior_pid.

	* sparc-tdep.c (get_saved_register):  Handle window registers
	in a dummy frame correctly.
