[ELDK] PPC_6xx does not have brlock.h

An application which includes linux/config.h?  This is not something a
userspace app should ever do.  Can you enlighten me what they try to
achieve with this?

Urgh.  Again, why does the application need to include this file?  I
consider this to be a bug.

On a quick check I find brlock.h in a 2.4 kernel and in there it looks
like something which can only be used inside the kernel.  So I do not
see why a userspace application would ever need to include this file -
so this again looks like a kernelspace/userspace violation.

Can you tell us what the intended usage is?

Cheers
