It's possible these warnings are false alarms, but if they are not
then the code is broken, and it may get miscompiled by compilers other
than gcc. If we hide the warnings in the normal development
environment there is less incentive to fix the code, or even
investigate if we really have a problem.

On the other hand if gcc really is going to produce invalid object
code from our invalid source code then it seems sensible to enable
this for production. Perhaps this flag should only be added if
enable-maintainer-mode is not used?
