    187091 [vjoel path.b] Hm, any plans to migrate the One-Click Installer to VC++2003?
    187098 [halostatue g] The One-Click Installer for 1.8.2 was on VC++2003. However, becausethe most common free compiler (mingw/msys) was not compatible with itand any number of other reasons, 1.8.4 is now based on the Ruby 1.8.4build built in Japan (I'm sorry; my mind is blanking on the name ofthe site and the person behind it) which is built with VC6 -- and isNO LONGER AVAILABLE to users.
