You should be using a cross-compiler

The tutorial seems to be assuming the use of a hosted compiler, but if anyone wants to do serious development you should be using a cross-compiler or you will run into problems.

I use a system compiler, and I do OSdev with it and it works fine. Don't say stuff like you WILL run into problems. You just copy pasted from the OSdev wiki and opened an issue that hardly even has anything to do with the project. This isn't serious development, you don't need a cross compiler.
