If we do this, I think we should actually quote something of the warning 
rather than just giving a line number that may be meaningless after source 
code changes.

There are quite a lot of -Wno- options in various Makefiles in the source 
tree.  It would be good to review them and see if some are in fact no 
longer needed, or if the relevant code can be fixed to avoid them.  
Generally any such workarounds for warnings need occasional review to 
avoid them staying around longer than necessary and so meaning warnings 
pointing out real problems get missed.

I'd suggest -Werror is only applied to installed code not testcases, if 
possible, since testcases can have good reason to do dubious things that 
will generate warnings.
