wine users - Nov 2010 - native and builtin dll

i was often confused.

Native DLL: in PE  format. butnot fake DLLs.
builtin DLL:  ELF .dll.so files in /usr/local/lib/wine


builtin  DLLs are ELF, they have NTIMAGE Headers and can link native DLL
or linked to native DLL. right?

after calling __wine_dll_register, a dll.so is loaded.
I did not see the code to link pe32 DLL.

if dll.so can not link pe32 dll. why winebuild creates import thunks?

What problem are you trying to solve?

sorry, 
1)whether can I link a dll.so to a  dll.so,or DLL
2)whether can I link a DLL to dll.so.
3) whether can I make windows DLL with winebuild
without wine librariesso that It can run on xp?
