In compiling gatping (0.2), I get lots of interesting things :-/
# make
gcc -s -O2 -Wall -o gatping gatping.c

I created a patch to fix most of them; it is attached. I also created a
minimal Makefile to allow a make.
I've also created a lrp/* directory for gatping (but not Echoware)..
I've also created a gatping package - also included.
