I've described the specific issue with converting this code to C in cover
letter: how to make compiler to generate 32-bit code for a specific
function or translation unit, without breaking linking afterwards (-m32
break it).

I would be glad to convert it, but I'm stuck.

Do you have an idea how to get around the issue.
