Unless a new compiler or optimizer suddenly became "smarter" and
recognized some new possible mistakes that the previous one didn't.
Or, in the case of this bug (see the link that someone gave earlier in
this thread), that the warning only happens in some rare combination of
#ifdefs, where, for example, some variable is defined but never used.

Since the goal of the user is to *use* the program (not debug it), and
since issues like unused-but-set variables certainly don't prevent
the program from being used, I think it's stupid for the user's
compilation to abort when the compiler discovers such issues

Down with -Wall -Werror!
