Add a check for bzero() or memset(). This requires some stupid thrashing

to deal with the stupid FSF compiler, which has ArCaNe KnOwLeDgE about bzero
and memset and will fall over and die if you don't provide arguments for
the functions even if you don't #include <string.h> (or whatever include
file has the prototype)
