Although Clang is getting away with this, there are some very noisy warnings in
GCC's -Wall, like:

-Warray-bounds (only with -O2) -Wsign-compare (only in C++) -Wuninitialized 

For sure, some -Wall warnings should be enabled by default, such as -Wformat, 
-Wformat-security and -Wnonnull (like Ubuntu does already).

Other candidates, in my opinion, are -Wimplicit, -Wcomment and
-Wsequence-point.

I think we should not.  I did not write in the thread on the email list because
I was busy at the time.

I have only seen two bug reports asking for it in the last 6 years (this is one
of them).

I think we should spend more time in improving our documentation rather than
enabling -Wall by default.
