Because those calls are generated after cpp has run so they do not use
#define memset.  We end up with two classes of memset, most using the
macro but a few using the function.  When this problem occurred in the
context of gcc 2.7 and 2.[02] kernels, the response was always to
change the source code to prevent gcc generating code that we did not
want.  If that decision is going to change, it needs to be run past l-k
