Right... How about replacing?
"available, e.g. during bootstrap, this gives the correct answer only..."

with

"available, e.g. while compiling the Emac source code, this gives the 
correct answer only..."

If I am not able to make it work, then I will post here the final
patch so that someone else can push it.
