You've failed to grasp (again) that the important word in Pat's
sentence that I didn't notice in his earlier emails is "Windows".
Sensible OSs don't prevent users from helping developers like that.

s/experienced//

Again this is only really an issue on Windows (and somewhat on Macs),
because decent compile environment that doesn't cost the earth is
hard work to set up.  On Linux, it's trivial.

But in this case you're just plain wrong.  Carl Eugen isn't asking Pat
to recompile anything.  He's asking him not to use external libraries,
i.e. not to select the x264 codec, which is a rather different
proposition.  I'd suggest that you owe him an apology, but knowing
how poorly you take his rather abrupt usage of English, I'm not
holding my breath.
