How do I use GNAT to develop an OS kernel?

- Subject: How do I use GNAT to develop an OS kernel?
I'm wanting to develop a kernel in Ada and would like to know how I go
about preparing the compiler for this task?
I have dabbled previously with this on earlier versions of GNAT. I
utilised the following pragmas:
just to get a basic hello world style kernel working. Now this old demo
of mine doesn't compile with the newer compiler, so I'm wondering what
exactly should I be doing to target bare hardware.
I intend to target IA32 and ARM using QEMU to start with using x86-elf
and arm-elf compiler targets (for example) or maybe dwarf, who knows ;D
as yet. The first task is to get a bootable hello world style image
again using the newer compilers.
I do not intend on doing what some people do and port the runtime to the
hw and then base everything off that, what I want is a proper kernel.
Can anyone help me with this?
