The .inc files are assembly language files that "stack up" or include,
in order, on top of crt0.base. These execute first, and eventually move
the C-code (and decompress it if necessary) to RAM, ending at c_start.S,
which jumps to the C-code. The .inc files do things that are necessary
as a prelude to running C, which needs RAM (ie, a stack).
Each .inc file must jump around its data, it is expected to execute top
to bottom and flow to the next file included below it.
