[U-Boot-Users] latest (1.3.1) doesn't compile: files missing
There are two missing files from the distribution that prevents uboot from compiling.
stddef.h is included by a few different things, but can be a blank file.
stdarg.h is included by a couple of things, and can be a trivial implementation (attached).
These are both host includes, and likely shouldn't be included at all in the boot loader code proper.
This is when building the MPC8548CDS config.
I also get link errors on this out of the box:

Are these to be expected with binutils 2.15 and gcc 4.2.1?

What sort of toolchain are you using?
stddef.h is included by a few different things, but can be a blank file.
stdarg.h is included by a couple of things, and can be a trivial implementation (attached).

It seems you have a toolchain issue. This is not a problem with U-Boot code.

binutils 2.15 and gcc 4.2.1. The problem turned out to be the combination: gcc 4.2.1 produced code that binutils couldn't assemble properly. That was what was causing the relocation error.

The two include files aren't a toolchain issue. They can't be because uboot's makefile has said not to include anything from the standard include files. These files aren't included with u-boot.

They are - see previous message.
uboot's makefile has said not to include anything from the standard include files. These files aren't included with u-boot.
stddef.h is included (as include/linux/stddef.h); only host files in tools/ reference host include files.
And stdarg.h has to be provided by your compiler.

I think I should be a bit more explicit:

U-Boot already has a stddef.h (include/linux/stddef.h) which gets used for all U-Boot related compiles.
stdarg.h is included by a couple of things, and can be a trivial implementation (attached).
stdarg.h is a compiler provided file and thus has to be provided by your toolchain.
As mentioned before, I don't think that any changes to U-Boot code are necessary.
