Hi Filip:
Yes that could work better so we have a single DLL and that does not consume RAM anyway ReactOS would be ready for a CPU downgrade too. btw I built some cvs snapshot today and saw the OARCH flag in the configuration file, the cpls being worked out mesa building (usable?), some text strings not in source code anymore. It failed at some point compiling explorer and I really needed to leave home but i'll keep playing with it for a while (not too much am on final exams almost)
Regards Waldo

Another thing that could be done is to detect the CPU at some time during initialization and use one of two ntdll (on with SYSCALL an another without it).
It's implemented in WinXP much easier than that. On startup it's detected if the processor supports SYSCALL and the appropriate code is sticked into the user shared page. The user mode code then just does jmp at the place in user shared page and it uses the correct code. Easy ;-)
