backward compatibility of gcc on xcode tools.

Hi,
I am using os X 10.3.9 with xcode 1.5 and gcc 3.3. I believe this
version of gcc is pretty old now and am thinking of updating to gcc 4.0 or
later. However I don't want to reinstall all the packages that I installed
using fink and darwinports and some more, by compiling the source code. Is it expected that all the compiled libraries will continue to
function and link smoothly if I make this upgrade?
thanks,
--a.

If you upgrade to Xcode 2.x then it has both gcc 3.3 and gcc 4.0, and
you can select which one is ued by default (gcc_select). So you can
still use gcc 3.3 for your crusty old open source projects and use gcc
4.0 for more up-to-date stuff.
