Added freeldr and hal from PPC branch, along with needed headers and build changes. Next ntoskrnl and add ppc dir under libcntptr, which didn't exist when I forked. svn path=/trunk/; revision=28793 2007-09-03 01:57:36 +00:00			`/*`

- Move from using include guards to pragma once. - Whilst this is non-standard and potentially makes the code less portable, it's supported by both gcc and msvc and should bringg increased compilation speed due to its optimized behaviour (doesn't need to invoke the preprocessor) - Patch by Amine Khaldi [amine.khaldi@reactos.org] svn path=/trunk/; revision=45685 2010-02-26 11:43:19 +00:00			`#pragma once`
