Huh? Stable or development LFS?
Stable, i.e. 6.1

This is from the current development LFS LiveCD, not FC4, but I assume
the problem is the same:

Does passing --disable-werror help?
No, as there is no -Werror on gcc command line, and compilation passed
past many warnings above that error.
Or maybe we just need to add
the required GCC4 patches to the Binutils version used in stable LFS as
errata.
In binutils-2.16.1, they moved "struct relax_type" definition from
gas/tc.h to gas/as.h. See backport in the attached patch. This does help
compiling binutils. If there are no other problems further in the build,
please include the patch into 6.1.1 instead of blacklisting gcc4-based
hosts.
I'm a bit mystified as I have received successful bootstrap reports of the
DIY build from FC4 using pretty much the same packages as current
development LFS.
But the problem is in the "stable" LFS.
Blacklisting any current distro is a major cop-out IMHO. We should be
giving top priority to fixing these kinds of host bootstrap problems.
Probably you are right that such known "host bootstrap" problems should
be fixed in stable dot releases. The main problem here is that they pop
up only after the release, and there's no way to predict them. Some
warning about the possibility of unknown "downgrade" issues of this kind
is still appropriate. Let's see if today's DIY-linux buildability
survives after FC5 or FC6 comes out.
BTW also the following text should be changed in the book:
--disable-nls
This disables internationalization as i18n is not needed for the
temporary tools.
Should be:
This avoids the dependency on gettext being installed on the host.
