I'm still working on this part, I feel like in order to have a fully freed device, I should be able to use any and all free software on it. In order to have that ability, I have been working on getting GCC natively compiled on the Kindle, however I'm going to need to do a bit more research before this part of my experiment comes to fruition. I have tcc in the Kindle, so I have something to start with, but I'm going to have to figure out how to make tcc compile an initial GCC, Make, and glibc, so that gcc can bootstrap itself.

I found this which I used to compile and intsall a cross compile from the gpl distrobution of the kindle source from Amazon, I successfully managed to compile a simple hello world progam with it. I am still trying to figure out how to tell it to compile gcc, glibc, make, and the other couple prerequs for gcc to bootstrap itself.
I'll be updating this page with more information on this as I learn.
