Sure, that was what I was thinking of. It is actually already the same
with strdup().

I put the following into miscutil.c; please have a short look and check
whether it is correct:

#ifndef HAVE_SNPRINTF
int snprintf(char *str, size_t n, const char *fmt, ...) {
    int rval;
    va_list ap;

    va_start(ap, fmt);
    rval = vsprintf(str, fmt, ap);
    if ( strlen(str) > n ) {
        syslog( LOG_NOTICE, "snprintf buffer overflow" );
        str[n] = '\0';
    }
    va_end(ap);

    return rval;
}
#endif
