In what way? It's not like the ./configure script will produce very =
different
results on alpha vs parisc, it doesn't even check for 64 bits/32 bits
differences. All this just demonstrated my gut feeling that compiling (
the kernel, for example) feels slower on parisc than it should be.

It's exciting to be involved in - I fully agree.
Good luck,
