If you really want to get everything right you have to write a linker
script. This also allows making the PE header the first thing in the
image. It's not very portable but it's easy to have a linker script
for each platform. I played a bit with that back when we were trying
to make the Visual C++ debugger work on builtin dlls, I may be able to
find this code somewhere if someone is interested.
