FYI, I am still compiling the weekly egcs snapshots and testing the Haifa
scheduler for improvements.  Just a few minutes ago, I put the 980502
snapshot up on beezer in case anyone's interested.  This one has the
scheduler enabled and seems to work fine under my limited testing
conditions.  If anyone wants to pick up the snapshots that I compile,

Very true.  I played with gcc 2.8.x for awhile before concluding that egcs
is superiour on the Alphas.  Plus, it just doesn't seem to have alot of
the advanced features that egcs does.
