After a long hard struggle wookey and I have succeeded in getting the bootloader for Balloon-3 to build with gcc 4.x Balloon svn contains the current source tree in "trunk". Work is continuing on fixing more compiler warnings and on general code cleanup. There are still some problems but in general it works and is usable.
