Just my opinion on this, I don't care enough to argue it more than this;
rm -rf <any directory> in response to configure, by default, is *not*
expected, or reasonable behaviour. Rather than having an environment
variable to turn this off, it should be the other way round. I can see
people getting caught out by this, even one of the students I was
mentoring stored things in the objdir (against my advice, mind, but all
the same).
I think it's a reasonable statement to say that people don't expect a
configure script to delete things, especially things it may not have
created. Either there should be a more reliable clean-up method, or I
don't think this should be default behaviour.
I agree the behavior is not expected if you're coming from a traditional
configure + make background. However, I believe automatic clobbering is
what the plurality of people want.
I think there is room for the UX to be better. For example, if we need
to clobber and are in an interactive shell, we can display a warning
message and give the user a few seconds to ctrl+c before clobbering.
Would that be satisfactory?
