Im not sure what you mean by this... Anyway, if you want to peek at my stuff, take a look at those 2 urls below. One contains various Ruby 1.8.7 Win32 builds (compiled using older Mingw). Other one is my gperf. All this will work on Win2000 and up. In case of gperf, Windows needs to be en_US build. Anything other will simple not work, because Microsoft with they wisdom, localized perf counter names instead aliasing them! Not smart, heh..
