* acconfig.h (HAVE_PRGREGSET_T, HAVE_PRFPREGSET_T, HAVE_LWPID_T,
	HAVE_PSADDR_T): Add them here instead of in config.in.

	* acconfig.h (PRFPREGSET_T_BROKEN): New define.
	* configure.in: Add check for broken prfpregset_t type.
	* lin-thread.c (gdb_prfpregset): New typedef, depends on
	definition of PRFPREGSET_T_BROKEN.
	(ps_lgetfpregs, ps_lsetfpregs, p_td_thr_getfpregs,
	p_td_thr_setfpregs, thread_db_fetch_registers,
	thread_db_store_registers): Use gdb_prfpregset_t instead of
	prfpregset_t.
	* config.in: Regenerated.
	* configure: Regenerated.
