dump latest klibc into the udev build tree

KLIBC is used as an internal makefile variable, it expands to either true or false right now. udev should use something else than KLIBC to allow build against the latest and greatest klibc version.

Why is this needed? I don't see the KLIBC variable needed in the latest cvs tree of klibc.

thanks,

But the udev build does not contain any of those "addons" in it's version of the klibc tree, right? So why would it matter to udev?

thanks,

Thats the reason why the subject line reads: dump the latest and greatest ...

like that:
rm -rf klibc/* ; cp -a klibc-0.94/* klibc
make KLIBC=true -j || echo patch missing

I build udev and klibc stuff in one go.

Ah, ok, that makes sense. I've now applied your patch, thanks.
