How do I install older versions of a package in 10.3

I am trying to install the intel C++ and Fortran compilers that requires libstdc++.so.5 and I have libstdc++.so.6 installed. I tried to use YaST to install the older version, but it is not listed in the repository. How can I get the older versions of software installed?

Thanks

here as u said there were no repos for getting them

so me times you have to install them manually

hope this link would help you…
http://software.opensuse.org/search?baseproject=openSUSE%3A11.0&p=1&q=gcc

it would be much help full to solve your problem if you provide which openSUSE version you are using now…

any way newer versions would provide good. than why dont you just do your things with the new gcc versions
