Yes, I'm following the development of egcs closely and I'm currently using different snapshots on SGI Octane, DEC alpha, and a Linux PC-cluster. The efficiency for numerical computations is very good now, and I'm looking forward to a version 1.2 stable on all platforms. Thank you very much for your efforts! Regards /Oskar Enoksson
