Well, I still don't understand why I need the target runtime to build the
cross compiler. I understand I need it to cross-build target applications,
or to cross build some system target libraries that the cross-compiler would
link by default with any application - like startup code or the like - But
for the compiler itself that doesn't make much sense...
(as a matter of fact I always get an xgcc binary before it fails but i don't
know what it is exactly...)

Is this more perverse than to run native linux toolchains in VMWare under
windows?

Where are those various schemes documented. I guess i'm more perverse than
you are, and that's probably what I'm looking for...

And what was the scheme to cross build for ia64 (or hurd) before their was
any binary libc for ia64 (or hurd) ? (No i don't want to do any of that, but
i'm curious)

Thanks

A+
