e8bd25cef9 Modify ping so that it increases the send socket buffer size if the 
user runs with privilege, allowing the sending of icmp packets with
larger size (up to 48k, the default receive buffer size in ping),
which is useful for network driver development testing, as well
as experimentation with fragmentation.

Without this, cmsg_len size should be smaller than necessary on alpha.

ebe70c8f68 More egcs warning fixes: 
o main returns int not void
	o use braces to avoid potentially ambiguous else

Note: The fix to natd is potentially functional in nature since I used
the indentation as the right thing rather than the struct semantics.
Someone more familiar with the code should double check me on this one.

    root-only.  -c count limited to 100 and defaults to 16 when ping run

d32ff0376f When a timeval is stored at the beginning of icmp_data, the fields 
are unaligned for access by the alpha, so copy the value to a variable
that is aligned.

When checking the returned data, be careful to avoid confusing the
size of the icmp header with the size of a timeval. On i386 these
are both 8, but on alpha, a timeval is 16 bytes. This means that
a packet sent from an alpha contains 48 bytes of data, not 56 like
on i386.

a2a0088805 Fix a problem introduced with a recent change that caused a hang with 
unreachable hosts.  Note that most of this consists of telling SIGINT
and SIGALRM to interrupt the system call, instead of restarting them.
Also try to get rid of some potential races Bruce didn't like; hopefully
they aren't a problem (potential or otherwise) now.
