Sorry I don't know any Oracle product that is "hard coded" with any specific GCC patch level. If specific libraries are required, they are installed by the Oracle software installation and located in the Oracle home directory. Please provide more details, such as software product, error message, or what you are trying to accomplish.
GCC-4.1.0-28.4 was probably the last known version required and available when the document was created. Also showing Oracle Linux 5.3 or later. It does not mean later software maintenance or bug fix releases do not work and that you should not or cannot install any OS updates.

If the OS version is not supported, e.g. OL 6, you need a Oracle product upgrade and cannot simply install older core system components, since it will break your system.
What is your OS version? What version of GCC do you have installed? Not accepted where? Please provide all details.
It is common practice and sometimes necessary to ignore the software prerequisite checks in the installer or at the command line when installing older products under current OS versions. I suggest to ask such specific questions in the appropriate product forum, or contact Oracle support.
Downgrading the GCC version installed by the OS installation is nonsense and the only thing it will do is to break your system beyond repair.
