Ah, yes, I originally wrote the script before gcc4.4 was imported, and
at that time the buildworld failed while trying to build gcc4.1.

I wasn't clear abaut the `inconsistency'; by `inconsistent' I meant that
the output of awk script differs between runs, and that's why I'm using
md5 command.  The script terminates after running 180 iterations, or
when the output of awk script differs from that of the first iteration.
