We have LWP and RVM cleaned up and working well on the Alpha processors.
The next big step will be RPC2.

The biggest problem is:

-   typedef long RPC2_Integer;
+   typedef int RPC2_Integer;

After that all hell breaks loose, but... the RPC2_Integer must become a
32-bit value on Alpha. Later on a 64-bit type could be defined, but all
existing (and working) platforms assume RPC2_Integer to be 32-bits.

Yes, but you don't see the hundreds of problems that are hidden by casts
and obscurity, such as in the rpc2 marshalling/unmarshalling code,

    *(RPC2_Integer *)_ptr = (RPC2_Integer)value1;
    (char *)_ptr += 4;
    *(RPC2_Integer *)_ptr = (RPC2_Integer)value2;
    (char *)_ptr += 4;

The compiler will not give you any warnings, but a lot of important data
gets lost or corrupted this way.

rdsinit will work on the Alpha, it just needs to have the right
parameters. It looks like some length is not big enough either heap,
static, or total segment length.
