How about

#define STRCPY(dest,src,n) strncpy(dest, src, strlen(src) > n ? n \
                                                           : strlen(src));

type of definions?  Simple, portable, efficient, and shouldn't overflow
[although it does require the programmer to ensure that n = sizeof(dest)].
Something similar could be done for strncat, with the comparison being
           strlen(src)+strlen(dest) > n ? n : strlen(src)
instead.
