In an open-source project I'm working on, it's custom to not create 
anything that produces a warning, and to get rid of all warnings that 
get reported for any compilers supported. The reason for this is that 
it's very difficult to distinguish warnings that "are okay" and warnings 
that point to an actual problem, and then to keep a list of warnings 
that are okay in your head.

Of course the situation we look at is not the same as an open-source 
project, but I'm starting to get somewhat worried seeing "warning" in 
multiple mails recently. If at all possible, we should only use warnings 
for things that can always be avoided.

So as an example, if we always process tabs by converting them to 
spaces, and so they can always be replaced by spaces in the source, then 
a warning looks okay. If we want to keep the tabs, and therefore there's 
no way to get rid of the warning in some cases, then I'd look for a 
different way to solve this.

Regards,   Martin.
