My host environment:

[alex@localhost ~]$ gcc -v
Reading specs from /usr/lib/gcc/i386-redhat-linux/3.4.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux

gcc version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)

And run /mnt/lfs/tools/bin/gcc -v(same as g++ -v ) ,It listed like this:

[alex@localhost /mnt/lfs/tools/bin]$ ./gcc -v
