I disagree there. Where is it stated in the standard the compiler
is allowed to "optimize" calls to function A to map instead to function B
entirely under the covers for me?

Fine..So it's a non-standard extention. In that case I pose the question:

Does it violate the principle of least surprise that the compiler is deciding
to call entirely different functions for me because it decided that was 
"optimal" when all I did was specify -O2 or -O3?

Certainly does to me (and I'm sure many others). This is why other extentions
that were in left field should require an explicit -f option to enable.
