I've been using -Wall (not -Wextra aka -W) for quite a while now.  In 
fact, that was one of the major reasons to recode a lot of the funny 
casts in the interpreter.  I think it's actually clean now, for gcc 
anyway.  The unused parameter can be noisy, because of callback 
functions that all share a similar prototype.

Trying to compile warning clean may cause some problems.  The code 
required that compiles warning-clean across multiple compilers that have 
different ideas of what's good and bad, can produce some really 
contorted code!  I tend to think it's better to standardize on one 
compiler to be clean on, and gcc is a clear winner here because that's 
what most people will see.
