Qt supported Windows 95, until we dropped it in version 4.4 (I think, maybe
4.5). The reason was the lack of W APIs causing us to have to maintain a
double set of everything, thus adding to the cost of maintenance of the
codebase, for too little gain.

The issues were never the low-level API like files and streams. Those problems
had usually been solved for a decade (though there were certainly bugs, like
trying to deal with CRLF in a transparent manner). No, the problems were the
higher-level things, like dealing with graphical objects, text formatting,
hardware access, hardware-acceleration, etc.

I commend you for even trying Win95 and DOS, but what for? What real-world
purpose does it serve to talk about those?
