No, if I did get the comparison failures, it seems every single file was
different. It only happened for Solaris 11 bootstraps (on different
machines running either 11.0 or 11.1, with either as or gas, with a
vanilla tree or your patch), and was totally intermittent. So far, it
seemed to affect Solaris 11 only, though, Solaris 10 didn't show it.
I still haven't managed to investigate more closely.
