If you apply the patch below to Makefile, it will cause make to exit 
with an error code instead of success if there have been any errors (i.e. 
there are more than 8 lines in error.log!). It currently always exits with
success which is arguably not correct behaviour.

After this is applied you can do
./configure && make && make install
so it will only continue to make install if make exits with a successful 
return code.

It would seem like a good idea to apply this patch or a variant to CVS; 
does anybody disagree? Perhaps the format and generation of error.log 
could be tidied though; maybe now would be the time to do that.
