Optimization should have little to do with it --- I never build without 
optimization, and ident always worked just fine.

Our source files go quite a bit out of their way to make sure those 
ident strings are hard to optimize out, as a side effect of making them 
acceptable to picky compilers.  Well, at least I don't think I've seen 
any optimizer yet that dared strip those things.
