* m68k-stub.c: Remove ansidecl.h and the few uses of it.
Stubs should stand alone as much as possible. * source.c (show_directories): Avoid printf_filtered length prob pointed out by Jonathan Stone. * i960-pinsn.c (MEM_MAX, MEM_SIZ): Set upper limit properly to avoid accesses beyond end of table. Fix by Lee W. Cooprider, <Lee_Cooprider@vos.stratus.com>.
