Well, '-O3' might. But we use '-O2' because '-O3' costs a lot of
compile time, but has precious little effect on run time (and IIRC
can even hurt it, for reasons that I don't at the moment recall).

As long as the headers are clean, two or three warnings on a project
the size of wx (with a rather old compiler) don't matter.
