gcc and glibc versions

Question

I have gcc 4.1.2 installed. I installed a new separate gcc (version 4.4.6) too using yum on CentOS. Now my question is, do these two gcc versions use the same glibc version or glibc is different for both of them? How can I find out? Secondly, is it better to have a newer version of glibc in terms of performance?

Answer 1

Both GCC versions will use the glibc version you have installed on your system. GCC packages don't (usually) ship a separate C library.
