Well, there are quite a few problems on these systems. NFS hangs
sometimes, some machines are frozen. On the other hand, it's a good
target for hackers, I guess :-)

Well, I also don't like that I have to do all kind of tricks to get
sane working (compiling my own make, LD_LIBRARY_PATH etc.)

On the other hand, they really have nice computers:

AlphaServer ES45, 4 at 1GHz, Tru64

time make -j4:
real 0m48.473s
user 0m39.115s
sys  0m31.299s

Slightly faster than yours :-) Well, I want to have one of those :-)
Quite fast if you consiere, that it's used by quite a lot of users.

I think that breaks other systems.

Fixed in CVS. There was just an #include missing that needs to be set
when these u_int types are only in sys/bitypes.h.

I had to increase the minimum autoconf version to 2.50 to get it
working cleanly.
