Doesn't sound to me either for the expert.  You're killing her
Makefile, her config.h, and possibly cause a full recompilation.
That's why I picked up the `user expert' solution.

How about keeping `user expert', but in addition to the warning at the
beginning of configure, putting one at the end, so end the user cannot
miss it.

Well, in fact, I'm somewhat against moving and changing things, but I
agree the solution I just proposed is unsatisfying.

How about introducing --force?  It's also something I felt could be
helpful for other `protections'.

Or have configure understand the concept of -W, -Werror.  The expert
could have WARNINGS=-Wno-error.
