To explain the problem: The missing symbol is s gcc4 only symbol needed
when C++ code is used and is provided by libsupc++.a. Which means two
things:
* There's a library which uses C++, but does not link against libsupc++.a.
Otherwise the symbol would not be missing. This is a problem that should be
fixed.
* When running a gcc 2 program only gcc 2 libraries should be used
(respectively C-only libraries). The fact that a gcc 4 libary is loaded
indicates that no gcc 2 version of this library is installed, which is a
build system problem.
The second part was likely caused by Philippe's recent changes, as the
revision you've tracked down suggests.
