Regarding gcc compatibility with libc

[Kal via Gcc-help <gcc-help@xxxxxxxxxxx>]

Hi,

As per my understanding libc is provided by distributions and the gcc is
compiled and linked against libc.

I have seen different versions of gcc linked with a single version of libc

How do we check the compatibility of glibc with gcc version?
Which version of libc should be linked with certain versions of gcc (say
11.4.0)?

With regards,
Kal
