It would be pretty nice if there was at least one sentence here as
to why this change is needed and/or wanted. Repeating only what
goes into the ChangeLog is not very useful.

Fundamentally my question is: Isn't -O0 the default anyway? Why
would it be necessary to specify this on the command line of any
test case?
