As a GCC developer, I can make an argument for either approach and which 
is best would be highly dependent on the context.

What I don't see is how this code is performance critical enough to 
worry about this kind of microoptimization.

My suggestion is to write clear simple code first, and only 
microoptimize if the code turns out to be performance critical.
