I use OSX 10.10.5 need to compile some c++ code with an old version of gcc, namely 4.3.4. I don't think XCode provide that kind of tools. I suppose there is a way to do that by hand. How can I do that ?

Confirming couple of points
- You are running OSX 10.6.8
- Current Xcode version in your machine is 3.2.4
Xcode 4.2 should work fine on your machine. I have a snowleopard machine at office running Xcode 4.2, i updated it via the Mac App store only. Ok. If this is not working via Mac App store, then go to your developer account (free or paid) and then download the Xcode version for Snow Leopard and install it manually. Just make sure you are downloading the Snow Leopard edition not the Lion edition. Please don't hesitate to ask for assistance :-)
Edit : Here i am attaching a snapshot of where to find the link . You need to scroll down and check in the Downloads section.
Apple's gcc binary is really llvm.
Mac:~ bmike$ which gcc
/usr/bin/gcc
Mac:~ bmike$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

You'll want to obtain gcc from homebrew or from source if you need gcc and not llvm standing in for gcc.
Good reading abounds on various blogs:

Once you've gotten a real version of gcc installed, you can export CC=/usr/local/bin/gcc or whatever else you prefer for setting the environment variable to match were you choose to store your now non-llvm-based compiler.

I have compiled older gcc in the past as a last resort.
brew install gccFrom there you can see if an older gcc is available or worst case, pull that source and compile it from the version of gcc you have running from above. It looks like you'll be able to use homebrew to get at the version 4.3 from the versioned source already in the tool:
