add an upper limit to -t
match the types of return values and the variables they are stuffed in
make the man page and usage() a little more consistantly ugly
less obfuscation.

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.

Fixes bin/6649 and removes the last abusive signal handler.
Use SO_TIMESTAMP to get the kernel to timestamp packets on reception.
Fixes bin/5658 and provides slightly better accuracy.
Explicitly zero and terminate the IP options when using -R.

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.

This isn't necessarily the best statistic, but it is by far the easiest to
calculate. Update the man page to be more explicit about precisely which
statistics are printed out. Revert some of jmg's bogus man page changes from

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.

this is a NO-NO
re-arange to just set a "please die immediatly" flag in the signal handler
and handle this in the normal thread.
also handle ping -f better on slow links by backing off a bit when
we get a ENOBUFFS from the sendto().

for each packet with a call to getuid for the -v case.

2) Must be root to run preload (OpenBSD ping.c 1.8)
3) Don't print all replies unless verbose and root (from idea in
OpenBSD ping.c 1.10 and 1.11) to avoid leaking information available
only to root.
4) Remove unused h: from option string to getopt.
5) Make the compiler happy with exit(0) (Lite-2?)

Do a better job of argument parsing.
Don't permit ping -f to a multicast address (very antisocial).
Don't permit -L, -I, -T options with unicast addresses.
Ensure that we ask for only AF_INET addresses (should close PR#2584).
Return <sysexits.h> error codes for failures. Document this.
Fix man page to identify the author and put sections in correct order.

Simplified average calculations. This also fixes potential overflow errors
and minor rounding inconsistencies (always round to nearest now).
Don't lose more SIGINFOs than necessary.
Print \r at the start of the status message. This clears the dots that
are sometimes left by ping -f.
