compile gcc and library

[Xin Tong]

I am looking for an older version of gcc ( gcc version 3.4.X). I can
not find it in my os software repository. therefore i decide to
download the source and compile it myself.  I am looking at this
download link and have a few questions.

1. does gcc-3.4.2.tar.bz2 include all the other tars (i.e.
gcc-g++-3.4.2.tar.bz2 ).
2. if i compile the gcc in  gcc-3.4.2.tar.bz2, is libc going to be
compiled as well ? there are also other libraries such as libstdc++,
is it going to be compiled.
3. is it possible to link again a library compiled by other versions
of gcc (i.e. a program compiled with gcc 3.4.4 and links it with
library that comes with gcc-4.4.6 ) ?
