XHProf PHP-extension - added Win(NT/32) compatibility


Hi Scott,
hi Facebook-Team,

first of all - Thanks for this really good piece of software - i like it very much cause it saved my day a lot of times! 

So i did some slightly changes to the source-files of the XHProf PHP-extension to make it compilable on Windows platforms. I also did some minor changes to some parts of the code and removed some unreferenced variables to remove compiler warnings.

I hope you like the changes and the added compatibility and looking forward to the intgeration of my changes into the facebook/xhprof repo with great anticipation.

I also hope that the sources will still compile on your system(s) and that you now can remove the note: "A windows port hasn't been implemented yet." at http://mirror.facebook.net/facebook/xhprof/doc.html ;)

best regards and greetings from Germany
