FYI only: I've just checked that simply using "(void) fwrite(...)" is not enough
to silence GCC, so we really need this intermediate dummy variable. If somebody
is interested there are epic discussions about the (non-)sense of making fwrite
and friend wur at https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/305176
and http://sourceware.org/bugzilla/show_bug.cgi?id=11959, and probably more
places... :-)

       return true;
