I am sadly very new to git and its functions but i did the best i could, 
and i had build errors on the last attempt, but i have narrowed this 
down to three commits. Find the out put of git bisect view --stat 
attached with these commits included. Now i may be wrong, but it appears 
that only the commit in realtion to 64 bit memory maps will affect my 
system (as i am running x86_64) . For extra details, it seems that 
commit was to fix an issue with Macbook gen 5 rev 2, where i am using a 
gen 5 rev 3. I will try to finish the bisect once i have received help 
about this build issue.

Your time is appreciated.

Sincerely

William
