 Hi, thanks for the prompt after the thread got hijacked :)  I'm not
at my best at the moment, and I haven't built for 32-bit in a very
long time.  But I'm now at my desktop instead of ssh'ing to the
server from a tty on the netbook, so let's see if I can offer
anything -

 I will assume you followed the book's order :)

 Not wrong, just different :)  If you work out where these files are
(i.e. step up a directory for every '../') you will see that they
actually are in /usr/lib in both your result and what the book
expects.

 In my own 64-bit logs they have ... 4.7.1/../../../lib64/crt1.o
which implies that the book's version is expected on 32-bit.

 On 64-bit I get an 'Ignoring nonexistent directory' message,
followed by /usr/lib/gcc/.../include /usr/local/include
/usr/lib/gcc/.../include-fixed and /usr/include-fixed.

 So, you are not referencing the gcc /include and include-fixed
directories, nor /usr/local/include.

 That seems to be correct - please compare it to the book - 3
matches, for /tools/i686-pc-linux-gnu, /usr/lib, /lib.  For this
part I don't see any error - please point it out if I'm wrong!

 So, at the end of 6.10 everything was good, but now the include
path is wrong (doubled /tools/include, and only /usr/include) ?

 Are you doing something unusual ?  That probably includes building
on a virtual machine, using the package_users hint, and building on
mingw or whatever on windows.  Or using minimalist packages (dash,
busybox).  If this is a straight build linux from linux, did you
check the host against the Host System Requirements in the preface ?

 Sorry, I'm struggling to understand what has caused this
difference.
