Re: gdb emacs reporting 'Function "x_error_quitter" not defined'

    I think that is not a good idea.  Compiling with -O2 and with -O0
    produces two very different programs,

It produces two distinct executables, but "very different" is an
exaggeration.  Bugs that depend on GCC optimization are pretty rare.
I have found that turning it off facilitates debugging, so I always do
so.  I recommend this to others, too.

However, every time I rerun configure, this customization gets lost,
and I have to do it again.  I often forget to do it again, until I
once again run into inconvenient inlining and have to recompile.  It
would be nice to fix this annoyance.
