Building on the AMD64

[Marco Gerards <metgerards@student.han.nl>]

Hi,

Here is a patch to make it possible to build GRUB 2 on the AMD64.  I
hope this is the cleanest way to solve this, but please correct me if
I am wrong; I am not that familiar with autoconf, etc.

I have added a new set of types starting with `grub_host_'.  The types
like grub_size_t had a size depending on the host machine, which meant
grub-setup etc. also used a grub_size_t depending on the host size.
Still we need a grub_size_t specific for the host and it should be
accessible from grub-mkimage (otherwise the grub_module header created
on the AMD64 is too big).

The result from compiling on the AMD64 was tested on a PC and it
worked perfectly.  I also tried if it still compiles on a PC and it
still did.

What I didn't do is testing the result on an AMD64 box, I will do that
later (it means rebooting my desktop, which I prefer not to do that
often...).  There are some warnings on the AMD64 that do not show up
on the PC.  I have included all warnings in this email.  Especially
the warnings about the differ in signedness confuses me, I hope
someone else knows where it comes from and how to solve it.

I want to commit this patch ASAP.  I will commit it this Friday unless
someone has a problem with that.  I need this patch applied so I can
work on the PC port again, or at least test it now.

Thanks,
Marco

	* configure.ac: Accept `x86_64' as host_cpu.  In that case add
	`-m32' to CFLAGS.

	* genmk.rb (class PModule): Always use `$(#{prefix}_LDFLAGS)' when
	linking.
	
	* conf/i386-pc.rmk (COMMON_CFLAGS): Add `-m32'.
	(COMMON_LDFLAGS): New variable.
	(kernel_img_LDFLAGS): Include `COMMON_FLAGS'.

	(grub_addr_t, grub_off_t, grub_size_t, grub_ssize_t): Make type
	dependant of `GRUB_CPU_SIZEOF_VOID_P' instead on
	`GRUB_HOST_SIZEOF_VOID_P'.

	* include/grub/kernel.h (struct grub_module_header): Type of

	change to `grub_host_size_t'.
