linux-alpha build

Here are some warnings I get when building 1.62 on my Alpha under Linux.
If anybody has too much time on their hands they might want to look into
fixing these.

Note that under Linux the socket functions (accept and so on) use a
`size_t' to specify the buffer length, as POSIX requires. This is
significant because an `int' on the Alpha is only 32 bits, whereas
addresses (and hence sizes) are 64-bit quantities (and so passing an int*
to a function that expects a size_t* will potentially result in it
clobbering the next four bytes of memory, which isn't terribly nice).
