gcc/egcs on the alpha do not optimize as well as they do on the intel
chips.  That is being worked on, and hopefully 1.1 should bring some
significant improvement as the improved egcs scheduler (which is not
currently enabled due to stability issues) should be integrated by
then.

Switching to gcc would hurt your performance, and likely introduce
bugs into your code.

So, what are the chances that, on the off hours, you could run package
compilations? :-) Your machine has got to be about 20x faster than the
UDBs that are doing most complation...
