Hello,
I am trying to have various GCC environment in parallel to make some

You can completely separate two GCC environments alternating installation root with --prefix=PREFIX option of configure script. Thus you can switch between configurations overriding PATH and LD_LIBRARY_PATH like this: PATH=$PREFIX/bin:$PATH LD_LIBRARY_PATH=$PREFIX/lib64:$LD_LIBRARY_PATH LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH

Otherwise you can use same installation prefix for all configurations and switch between compilers using '-V_version_' option of gcc driver.

environment. Does C libraries have to be available for the various
compiler version ? Does C++ libraries have to be available for the
various compiler version ?

Yes.
