I'd be quite worried if they went away. The linker is reporting that
the compiler generated incorrect code[1]. I saw the same errors with
BFD ld. If you have a linker that is linking it without errors, I
wonder what it's actually putting in the binary...

[1] If anyone cases: someone from Apple decided to make block
descriptors public symbols with mangled names, rather than internal
symbols. This is a win most of the time, because it lets the linker
deduplicate them, but unfortunately they put the Objective-C type
encoding in the name. On ELF platforms, @ is the separator between the
symbol name and the symbol version, so block descriptors ended up
appearing as versioned symbols. This is now fixed in clang, to replace
the @ character with something else ('\1', I think).
