Alot of this drop of support is mostly due to the compiler dropping support, lack of testing and laziness on the developer side. All of the above is pretty common knowledge except for the fact that Mingw-w64 still compiles executables for <XP. I can confirm that Mingw 6.0.0.3 still compiles work executablesfor XP and above (and XP is still officially supported_ and if the proper MSVCRT.DLL used on 95+,NT3.50-2000 then those works too. It looks like bochs does support Mingw so I'd just post in that bug report a request for mingw and msvc builds on the download page and then state in the website that the mingw executables are for XP and above and the msvc executables are for vista and above. This should be no extra work except for uploading to the website since they should already be testing with both msvc and mingw anyway.
