I think it might be a better idea to -Wno-unused, since the only sorts of
warnings one wants to ignore building NDEBUG are the variables which are
otherwise unused. For example, if someone does something like:
int foo;
assert((foo = some_function()) != 0);
printf("got foo=%d\n", foo);
We *really* want to have that warning be an error, as foo is being used
uninitialized, and the code is broken.
Thanx,
juli.
