* 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>.
