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).
