GCC 7.3.0 will not compile, even with everything correct in version-check.sh.

I'm trying to compile GCC 7.3.0 as stated in 5.5 in the LFS book. The error messages I am getting is as stated in this hastebin as well as my version-check.sh output.

Thank you for taking your time to read this.

Welcome to LQ.

Just a thought: The book says gcc-4.7 or later, not sure it means a gcc with 192 changes.
I.e. the Debian compiler gcc-5 used by Ubuntu 16.04 got 192 patches added at gcc build time.

My test build, using an original gcc → gcc54, g++54 (Not LFS configure options):

Code:

cd gcc-7.3.0/
tar xvf mpfr-4.0.0.tar.xz && mv mpfr-4.0.0/ mpfr
tar xvf gmp-6.1.2.tar.xz && mv gmp-6.1.2/ gmp
tar xvf mpc-1.1.0.tar.gz && mv mpc-1.1.0/ mpc

cd ../ && mkdir build-gcc730 && cd build-gcc730/

export CC=gcc54 CXX=g++54 && ../gcc-7.3.0/configure --prefix=/usr/local/gcc7 --program-suffix=7 --enable-languages=c,c++ --disable-multilib --disable-libstdcxx-pch
make && sudo make install

... No errors.
