Why the change in text size? If moving stuff around in headers affects
the final result, I'm thinking that you did something wrong.

The merge for x86 did a lot of file manipulation, but Thomas and Ingo
would always test that the binary result was the same. If the binary
result is different, then something went wrong with the file
manipulations.
