My only guess would be binutils/gcc docs.
I think that is the only use of the LIB_PATH,--with-lib-path. I read about it in binutils-2.18/ld/README and also searched the various configure scripts in the binutils-2.18 directory (only ld/configure deals with the --with-lib-path option). >> The gcc pass 1 is also configured with CC="gcc -B/usr/bin/", >> and this gave me the impression that the gcc pass 1 was >> actually not being built againts the binutils pass 1. >> Does this have to do something with the fact that >> the gcc is compiled (according to the LFS book) three-times? >> >> > The -B /usr/bin tells the HOST compiler to use the HOST binutils.

Well, yes and no. No because --prefix tells the configure script the path where to install the package (the explanation of the --with-local-prefix is in gcc-4.3.2/INSTALL/configure.html). Yes because the new gcc compiles itself once it is compiled by the host gcc. During my experiments, the gcc-build/intl/config.log contained line: [ configure:2121: /media/baracuda/bfu/LFS-6.4/root_partition/sources/build-gcc/./prev-gcc/xgcc -B/media/baracuda/bfu/LFS-6.4/root_partition/sources/build-gcc/./prev-gcc/ -B/bfu-tools/i686-pc-linux-gnu/bin/ -g -O2 -fomit-frame-pointer conftest.c >&5 /bfu-tools/i686-pc-linux-gnu/bin/ld: cannot find -lc ] This tells me that the value passed to the --prefix and --with-local-prefix configure options is later passed to the -B option, when the new gcc is compiling itself.
