[coLinux-devel] No more DDK dependency!

[Dan A. <da...@gm...>]

Good evening,

I've successfully managed to build and test linux.sys using the GNU 
toolchain. I used ReactOS's helper.mk, pointed by Steven Edwards to 
generated the rather complex command line sequence that achieves this
goal (look at the patch below).

Thanks for Nir Perry for encouraging me to try this method further than
I thought.

Next coLinux release can be built on a Linux box entirely, using the GNU
toolchain. However, w32api needs to be patched and built from source, 
because there is a mistake in one of the kernel imports defined there 
(I'm mailing the author).

Would one of you like me to maintain precompiled binaries of a cygwin 
cross build tools for Linux, as .deb and/or .rpm files, so that the 
others won't have to mess with setting up this build environment?
