turns up lots of information, including people reporting

performance measurements.

Thanks for the reminder. There is much more on getting it to work under
various linux variants than anyone attempting to do it on windows. And
no-one there seems to have an easy time getting it working either. Why am I
trying on windows? It is what I have to work with.

I'd really like re-compiling everything to be a last resort! I'm not sure
that it should be necessary and if I tried it and it still didn't work I
couldn't be sure that I hadn't made a mistake somewhere.

 It would also be great if I could end this with step-by-step instructions
to help the next googler / svn.haxx.se user achieve the same thing.

Thank you,

Matthew
