--- Comment #52 from H. Peter Anvin <hpa at zytor.com> ---
I have updated the ABI document:

https://git.zytor.com/users/hpa/segelf/abi.git

... and added some sample code including hopefully-correct linker scripts at
...

https://git.zytor.com/users/hpa/segelf/samples.git

This requires the latest binutils tree I have at:

https://git.zytor.com/users/hpa/segelf/binutils.git hpa/seg16

... because I had to change the overflow behavior of R_386_SEG16 in order for
the PSP to be handled correctly.

I haven't written up an elf2exe program just yet, but at this point I'm pretty
sure it is trivial to do; with the linker doing PIE linking the rest of the
work is just mangling the relocations and filling in the EXE header.

Obviously, native EXE relocations cannot handle linear-address relocations
(R_386_RELATIVE).
