By "legacy" I meant only "compiled pre-change", not "deprecated" or
anything like it.

Or we could blow off ABI compatability.  We've done that before.

1.x executables that use nested functions crash under 2.0, is the first
example that comes to mind.  (Yes, I know why they do, and I think I
even mostly understand why the change was made, but really, given the
nature of its major benefit, I don't see why pre-2.0 executables
weren't grandfathered.)

So you're talking non-standard C code which used a GCC only extension?
