Not to mention, what if you're debugging, and part of your program is
compiled *with* and part *without* optimization?  I've lost count of
how many times I've had to do that, but each every one of them I sure
was glad when the compiler turned out not to be outsmarting itself.

No, you say, either you optimize, or you don't; half-half is asking
for trouble!  Sure is, but when the optimized half is some commercial
library your site doesn't even have the sources for, there isn't much
you can do but ask for trouble and hope it's going to be out of stock.
