No dice. CPls are DLLs that export a function - CPlApplet(). winegcc coughs on dllexport. - not implemented. I've been hacking at it for days on end now. Result: CPl can be compiled under windows and run under wine. CPls compiled with winegcc don't export that function => not treated as control panel applets. software to aid anyone: dllexp.exe. Download and run on any dll/cpl of windows, you get exports in it; run on wine dlls - nada. (hence, No Template in wine's source. Twain DLL exports some methods though.)
MICROSOFT ISSUE: EASY TO DISTINGUISH BETWEEN WINE DLLS AND WINDOWS DLLS.
If dllexp.exe can do it, so can they. Solution: M$ implements a code that *checks for a dll version* (based on what the DLL exports). Doesn't find export => coughs and dies with an "Incompatible DLL version". Happened before with OS2 / Windows. Maybe has happened now with all M$ that cough on wine.
Not enough intimate knowledge => can a soft cough and die based on a call to a DLL export which isn't there, without being designed to do so?

__declspec(dllexport) is a MSVC-only feature. Hence, when compiling with gcc (even using winegcc) it won't actually export the function. As has been stated before, you need to use a .spec or .def file to export it.

A DLL compiled as a winelib DLL won't be parsed by a tool that reads PE DLLs, because winelib DLLs are Elf shared objects. Use winedump instead.

Yes.

Precisely. Easy to distinguish between wine and doze Dlls.

I did. It dumps the CPlApplet() function nicely from all cpls (including one I made in Delphi).

Wine is easily detectable anyway. Just look at the Wine regkeys, or try some Unix-calls. It's impossible to stop childish companies from blocking Wine.

I'm sure it must be possible to export routines in Wine .dll.so libraries via .def files or similar - whether GetProcAddress supports Wine "DLLs" is the issue. Even if for some reason it's not possible, I don't see that it would be impossible to detect that the .cpl file is actually a Wine DLL, and to use the appropriate dlopen-type routines to read it.
