  It all depends whether the C library is being dynamically or statically
linked, surely?

  If it's static, then helloworld will pull in printf, which will pull in
stdout and fprintf, which will pull in the entire libio, ctype.. virtually
the entire thing.

  crt*.o tends to be quite small by comparison.

  Perhaps what changed between the two versions is indeed whether libgcc is
dynamically or statically linked?

  Or perhaps I'm completely wrong.  It wouldn't be the first time...
