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!
