Submitted for your approval and testing, a slightly modified identd.
Please note, this is UNTESTED as of 09:13 EDT, Wednesday, August 13th.
I'm currently swamped, but will be attempting to run a few tests today.
Compiles cleanly on Linux.
[root@maezw /root]# gcc -Wall -O3 -m486 identd.c -o identd
[root@maezw /root]#
Any contributions, ideas, suggestions, please email me privately. If
you have an OS that it does NOT compile on, and you create a fix or
patch, please share with the entire list. Thanks, and enjoy! :)
