Where may I find alpha code forks like this gdb-7.10 support code, if 
just to practice building the lib and plugin. Perhaps I will be helpful 
here, but I have a lot of reading to do first; do another breadth-first 
scan, at some depth and with a little better awareness of all the 
current goals.

My first task is to build a 64-bit Ubuntu system and jump in immersively.


Thank you,
