I'll do that, thanks.

I've done it a lot with a i386-win32 compiler and a cross arm compiler 
builded with it. The Lazarus IDE supports fine that configuration. You 
just change the project compiler options (widget and target platform in 
code page) and the project is compiled for that conf. The new 
configuration with a i386-win32 compiler, a x86_64 cross compiler and a 
arm-wince cross compiler with the Lazarus IDE works. But, off course 
advise noted it. You should know better than me.

If it's not difficult maybe this can change ? Or there is no need ? 
Personally i prefer a "naked" system with only the sources plus the 
ppcXXXX.exe executable to build my dev system.
