Libnet-0.10.11 : Last time edited year 2001.
' make CC=gcc-2.95 ' will create 'libnet.a'
Apparently the compiler is to be as old as the code.
The last surviving gcc-2.95 is in Debian 4 Etch.
Click my name, send an email, and I will attach
libnet-0.10.11-1.i386.rpm ( 143 kB ) to a return mail.

May be you are lucky, and the lib can even be used for something.
