The next release of BIND/iX that I'm still debugging defines its own strdup()
as:

char *
strdup(const char *src) {
        char *dst = malloc(strlen(src) + 1);

        if (dst)
                strcpy(dst, src);
        return (dst);
}

Pretty much the same way that you created the strdup() function:

extern char *strdup(const char *);

PS: These examples are from gcc.
