I asked Xiaofan for example projects that do not do it, so can
you give some examples of those that do?

That is not an argument for either way.

I don't know about you, but I do not usually want any of the options
that are enabled by default (except for maintainer mode some of the
time).

Btw, $* is wrong (should be "$@").

If you're building a lot, you probably should run some ./build
anyway ;-)


Let's go with the principle of least surprise, so do what most
projects do (or the most authoritative ones).
