stl + g++-3.2

[Albert Cervera Areny <albertca@jazzfree.com>]

Hi,
I'm trying to compile a proogram I've developed using the standard string and 
vector classes and it does compile without problems using g++-2.95 but if I 
just change the links for g++ and gcc from 2.95 to 3.2 I get some errors as 
if string and vector classes where not defined. Should I add something to be 
able to compile it?
Here is the first part of the g++-3.2 output:

g++ -c main.cc -I /usr/include/postgresql -I ../wvstreams-3.70/src/include
