Compiling gcc 4.5.0 in red hat 7 - gcc

Question

Im having trouble to compile gcc 4.5.0 in red hat 7.
Im following the instructions from here ("The hard way", without libelf).
I use following versions:
# rpm -qa | grep -e libelf -e gmp -e mpfr -e mpc
mpfr-3.1.1-4.el7.x86_64
mpfr-devel-3.1.1-4.el7.x86_64
elfutils-libelf-0.170-4.el7.x86_64
elfutils-libelf-devel-0.170-4.el7.x86_64
gmp-6.0.0-15.el7.x86_64
libmpc-1.0.1-3.el7.x86_64
gmp-devel-6.0.0-15.el7.x86_64
While compiling, he doesnt find mpc.h:
checking for the correct version of gmp.h... yes
checking for the correct version of mpfr.h... yes
checking for the correct version of mpc.h... no
configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations. Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also
http://gcc.gnu.org/install/prerequisites.html for additional info. If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files. They may be located in separate packages.
So I compiled it.
Here is the working configure:
/opt/app/gcc/gcc-4.5.0_SOURCE/configure
--prefix=/opt/app/gcc-4.5.0
--enable-languages=c,c++,fortran
--enable-bootstrap
--enable-shared
--enable-threads=posix
--enable-checking=release
--with-system-zlib
--enable-__cxa_atexit
--disable-libunwind-exceptions
--enable-gnu-unique-object
--with-mpc=/opt/app/gcc/tmp/
At the end of make I get this:
...
ar rc libgcc.a $objects
ranlib libgcc.a
make[5]: Leaving directory `/opt/app/gcc/gcc-4.5.0_BUILD/x86_64-unknown-linux-gnu/32/libgcc'

make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/opt/app/gcc/gcc-4.5.0_BUILD'
make: *** [all] Error 2
After some research I found out, that texinfo was missing. Install texinfo got me to a new failure:
...
make[3]: *** [doc/gccint.info] Error 1
rm gcc.pod
make[3]: Leaving directory `/opt/app/gcc/gcc-4.5.0_BUILD/gcc'
make[2]: *** [all-stage1-gcc] Error 2
make[2]: Leaving directory `/opt/app/gcc/gcc-4.5.0_BUILD'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/opt/app/gcc/gcc-4.5.0_BUILD'
make: *** [all] Error 2
After some research I found here that texinfo has a bug. Now Im trying to compile texinfo 4.13a but again, I get into trouble with no clear error message.
Did anyone achieve to compile gcc 4.5.0 in redhat 7?
UPDATE
I can compile gcc 4.5.4, but ONLY IF texinfo is NOT installed ...
kind regards

Your errors 1. GCC requires a build directory outside the gcc-source/ https://gcc.gnu.org/install/configure.html
gcc-4.5.x cannot use the EL7 texinfo. Please install a texinfo from "the gcc-4.5 days" :
yum remove texinfo
yum install Downloads/texinfo-4.13a-10.fc14.x86_64.rpm
http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/14/Everything/x86_64/os/Packages/texinfo-4.13a-10.fc14.x86_64.rpm
GCC-4.5 : The bugfix version is 4.5.4 .
Note: The default build directory is $HOME/tmp/ (Or other dir. in $HOME). ... My build example :
cd gcc-4.5.4/
tar xvf mpfr-3.0.1.tar.xz
mv mpfr-3.0.1/ mpfr
tar xvf gmp-5.0.5.tar.xz
mv gmp-5.0.5/ gmp
tar xvf mpc-0.8.2.tar.gz
mv mpc-0.8.2/ mpc
cd ../
mkdir build-gcc45
cd build-gcc45/
../gcc-4.5.4/configure --prefix=/usr/local/gcc45 --program-suffix=45 --enable-clocale=gnu --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-languages=c,c++,fortran --disable-libstdcxx-pch --disable-multilib --with-gmp-include=$(pwd)/gmp --with-gmp-lib=$(pwd)/gmp/.libs
make
# make install
cd /usr/bin/
# ln -s /usr/local/gcc45/bin/gcc45
# ln -s /usr/local/gcc45/bin/g++45
# ln -s /usr/local/gcc45/bin/gfortran45
Using, examples : $ export CC=gcc45 CXX=g++45 FC=gfortran45 && ./configure .... .... $ CC=gcc45 CXX=g++45 FC=gfortran45 cmake ../
Result : "gcc45-c++-4.5.4-1.el7.x86_64.rpm" https://drive.google.com/file/d/15aRg-BPhuyaEyZA9Jy-iAyC21_pwN7nD/view?usp=sharing
Example with the older gcc-4.5.0 :
$ cd build-gcc450/
$ ../gcc-4.5.0/configure --prefix=/opt/app/gcc-4.5.0 --program-suffix=450 --enable-clocale=gnu --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-languages=c,c++,fortran --disable-libstdcxx-pch --disable-multilib --with-gmp-include=$(pwd)/gmp --with-gmp-lib=$(pwd)/gmp/.libs
$ make -j4
# make install ( No errors at all )
