* paread.c (read_unwind_info): Just assign to objfile->obj_private,

	* paread.c (read_unwind_info): Just assign to objfile->obj_private,
	not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
	the HP compiler in ANSI mode doesn't like.

	* main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
	based on USG, rather than defining HAVE_SIGSETMASK to an expression
	containing defined.  This is for the HP compiler in ANSI mode.
