Intel has a compiler that allows one to declare things are big or little endian and then things work. A certain large router vendor used it to port its software that was big endian only at a very deep layer to Intel x86... Linux marks things as beXX or leXX and uses static analysis to prevent mixing. There's a lot of prior art for the committee to choose from. Warner
