 From the looks of it, that would be good.

As far as my issue with -Wno-narrowing and the other errors, it seems  
to be from hosts that are using gcc < 4.7. Have you used any hosts  
which use gcc  < 4.7?

Cross-tools there is nothing in /tools/include at all before the  
install.

in the final-system when the headers are installed, if folllowing the  
boot method, eudev headers will be in /usr/include. WIth the chroot  
method, there should be nothing there.

Finally fixed.

I usually do that myself. We could add it or insert a note about it.

I didn't bother with Bison 3.0 as it was compiling a host binary with  
the target compiler so the host couldn't run the binary to continue  
the build.

I removed ac_cv_prog_lex_is_flex as it was being configured properly  
in the last 10 builds I've done. I didn't have an issue going from  
x86_64 to ppc either.

I don't know why that is cropping up sometimes. I've been using Debian  
Jessie as a host and the updated lfs livecd.
