The TTL and ToS of replies are now printed. Traceroute functionality was added. Portability fixes were made. This version should work on at least Linux, FreeBSD, OpenBSD, IRIX, and Solaris.
Flood mode (-f) was added. The -w option was changed to -i. The -w option now specifies how long to wait for replies. ToS bits can be set with -Q. A getaddrinfo() implementation was added for operating systems that don't have it, like IRIX.
This release adds a TTL switch (-T). It has transaction ID support (-t). It can track order replies and duplicate replies. A GSN "simulator", used for debugging (only answers pings), has been added. The build has been converted to autotools (no more hacking the makefile to compile on Solaris). A man page has been added. Some standard GNU features have been added (--help and --version).
