Under WPP this is error (E591, to be precise).

This may written as "*(char*)s++", but here is trouble with such code
(because casted value isn't lvalue). Fortunately, here two solutions. First:
#define memset(s,c,n) memset_ ((void*)s,c,n) /* PROTO.H */
void memset_ (byte *s, byte c, size_t n); /* PROTO.H and MAIN.C */
Second:
void memset(void *s, int c, size_t n)
{
while(n--)
*(byte*)s = c, s = (byte*)s + 1;
}
PS: Lucho, do you seen my letters?!
