I don't think this statement is accurate. The problem is "multiplatform" is ambiguous. If a "platform" is an operating system, multiplatform code is certainly allowed in Wine, though portable code is preferred to OS-specific code whenever possible. If a "platform" is a CPU, then with the exception of x86, assembly is not allowed, as there are so few non-x86 Windows binaries that this is essentially worthless. Similarly, the goal of Wine is _not_ to emulate the x86 CPU, so such emulation code is likewise not allowed in Wine. --Juan

Very likely but you run into the following: 1. Windows programs are written for the x86 processor. Is there an x86 emulator for the ARM arch? You could run wince / windows mobile apps which are often ARM native.
If no then are there any plans for multiplatform code in Wine? NO! Even MacOSX specific code is not allowed Actually we have quite a bit of that. dlls/winecoreaudio.drv, using a few macos specific opengl extensions in wined3d, etc. The important thing is that it is properly abstracted and not an #ifdef orgy.

Unfortunately WinCE isn't completely compatible with win32, so I doubt that'll work without quite a bit of extra effort. 2008/8/8 Juan Lang <juan.lang(a)gmail.com>:
At the risk of getting even more off topic, Objective-C is one of gcc's dialects and works on Linux and *BSD just as fine as on Mac OS X.
Yes, I know, and so is C++. Nevertheless, neither is allowed in And so is Fortran, for that matter :-)

Windows programs are written for the x86 processor. Is there an x86 emulator for the ARM arch? That's the problem I thought about. So it would be needed something like qemu-i386 or sth. for userspace emulation. > 2. Windows programs are mostly written for a minimum of a 640 by 480 pixel display. I know of very few devices that run at that, or higher, resolution. I'm talking about devices with 480x640/640x480 (Neo 1973/FreeRunner) and bigger display (800x480... like Nokia N810 etc.). > 3. Are the ARM processors 'strong' enough to run both a x86 emulator AND Wine AND provide acceptable performance of many Windows programs. My intention was not to run Windows games but simple programs (like Mikrotik WinBox etc.) and ARM processors clocked at 400-600MHz could be enough such basic emulation. >> If no then are there any plans for multiplatform code in Wine? > NO!
