Comment (by pierre.labastie):
I have saved the "build" directory for each ICA build of gcc. With the
-idirafter switch, there are no differences in the .o or .a files. So it
is rather clean? and I think we should make the change in the book (*).
But still there are differences in gcov...
Looking at the link command for gcov, it is found that it links with in-
tree .a or .o files, but uses the -static-libgcc and -static-libstdc++
flags. So I suspect it links against the libstdc++.a and libgcc.a from
/tools on first iteration, while it links afainst the ones in /usr on 2nd
and 3rd.
Let's try a diff of those libraries.
(*) Bruce also thinks that it is educational to have -idirafter (private
communication)
