Ok, so we need __enable_execute_stack then, I guess. I find it strange that some parts of libgcc can not be used in freestanding code. Does this happen with the unpatched version of GCC too? Maybe we'll have add some dummy symbols to make it happy. I don't think any of this will be actually needed when kernel isn't present. -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call… if you are unable to speak?
