I'm not an expert either. In a previous post, I noted that perhaps there
is some compiler flag in msvc that will help. If you don't take that
into account, the statement above makes looks like an anti "M$" rant.
Rather than cast aspersions on msvc per se, the intent is just to show
that much of the performance hit in Wx *might* just come down to how it
is being compiled. For now, the simple fact is that I *can* get a 2x
increase by compiling the same sources, and I haven't found a msvc
compiler incantation that will speed things up.

There is another benefit to getting a gcc build chain working though,
even if it's just for "release" builds. It will make it easier to
compile a unix version of WxSqueak.
