You should know whether you want a 32-bit DOS app or a 32-bit Windaube app

Native WinXP not possible ?

Theoretically YES

No or very bad only

Compile a 32-bit DOS app for DOS or a Win app for XP/Vista.

For DOS you need a 32-bit DOS C compiler first (CC386, DGJPP, OpenWATCOM). HX would allow you to use MSVC 6 also - via the PE format and API emulation approach, but then you have a problem with the GUI - see below.

If your app must run in both DOS and Windaube, the only acceptable choice is to compile a Win32 app using console or low-level-GUI-API only (thus DR-DR-DRAW, OGL, SDL, no Dialog-Box-ing or multi-"window"-ing) and run it in DOS via full HX with API emulation and HX GUI.
