Has to install gcc-3.4.6 under Centos 7

I tried to fix the compilation issue with gcc3.4.6. Can you suggest how I fix the following errors:

options.h is unchanged
options.c is unchanged

Why you want gcc-3.4.6 to be used with the CentOS 7 native C libraries ? 
(Some quite new glibc there)  The produced native toolchain
would produce executables which as default would only work on CentOS 7 
and newer than that releases. Not on CentOS 6, 5, 4, 3, 2, 1,
on old Fedora releases or RedHat releases...

One sane goal would be to get a toolchain on CentOS 7 which produces 
executables for some older CentOS (or something else) release
which had gcc-3.4.6 as its original native GCC or as a self-made updated 
native GCC. That using some old glibc as its native
C library.  This goal meaning producing a crosstoolchain to the old 
Linux release (building binutils and GCC to use the old
glibc as prebuilt in a $sysroot)
