Right, and if visual rust used a different dynamic lib format, you'd
have a problem. Similarly, if we ever want to change our so format in
an incompatible way, it seems we're in for some seriously complicated

What is the problem with using the stage0 compiler to first compile a
standard lib for stage1, and then a stage1 rustc? Isn't the current
situation, where (if I understand correctly) stage0/lib/libstd.so is
used both by stage0/rustc and stage1/rustc kind of asymmetrical and
