Build gcc-3.4 on Sarge fails with "No rule to make target `gnatlib-shared'"

[Lucas Barbuto <lucas@stabat.com>]

Hi,

I've been supplied with a C++ binary that I'd like to be able to run on 
my Sarge system. As I understand it was built on a recent Redhat 
derivative with a GCC >= 3.4. I also understand that this is not 
compatible with Sarge and the application won't run (which it won't, 
complains /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.4' not found).

In order to make it run, I figured I may be able to rebuild the package 
gcc-3.4 with GCC 3.4 on Sarge, install the packages into /usr/local, 
then run my binary with

$ LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH ./runme

But before I can test this theory, I need to be able to build the 
package. I receive the build output below.

Not being very experienced with compiler versions and shared libs, I 
have a couple of questions:

 1. Does the above approach sound logical, or am I wasting my time?
 2. Does anyone know how I can resolve the build error below?
 3. If I can't make this work, which branch of Debian has compatible 
libraries for C++ applications build with G++ >= 3.4 - testing or 
unstable? Neither?

Thanks in advance.
