Using -O0 produces a binary that's slower, but if it crashes or you
need to debug it, the information you can report is more full and
reliable. Letting the build use the default optimization produces a
faster program, but it's harder to debug.
What to do is up to you. I debug the development version of Emacs
quite a lot, so I always build the development snapshots with -O0.
