The built GCC is that from specific SPEC runs on the same machine.

vangelis, czerny and terbium us the head-64 sandbox, frescobaldi uses
the ipa-64 sandbox

so you can use the update log from around the same date.

Recently I changed it to be $[`date +%k`*99/23] plus the SVN revision appended.
before that it was date %s with the first 5 digits skipped for a long time.

script grepping
the output ;)

I'll tar the scripts producing the output up and mail them to you (privately).
