AMD64 and C++ compiling

[Andrea]

Hi everyone,
I have some compilation problems with my code written in C++ on
Ubuntu-Hoary[AMD64].
On my Debian x86 laptop with g++-2.95 and libstdc++2.10-dev all seems
ok, it compiles with no errors, instead on Hoary-AMD64 with g++-3.3.5 or
g++-4.0 with its own libstdc++ the same code gives me this output:

gcc -Wall  -c test.cpp
In file included from test.cpp:2:
primitives.h:10: error: syntax error before `::' token
primitives.h:11: error: syntax error before `::' token
primitives.h:18: error: 'list' is used as a type, but is not defined as
a type.
primitives.h:40: error: 'list' is used as a type, but is not defined as
a type.
primitives.h:54: error: 'list' is used as a type, but is not defined as
a type.
primitives.h:55: error: 'list' is used as a type, but is not defined as
a type.
primitives.h:56: error: 'string' is used as a type, but is not defined
as a 
   type.

primitives.h:73: error: `m' was not declared in this scope
primitives.h:73: error: invalid data member initialization
primitives.h:73: error: (use `=' to initialize static data members)
test.cpp: In function `int main(int, char**)':
test.cpp:32: error: `string' undeclared (first use this function)
test.cpp:32: error: (Each undeclared identifier is reported only once
for each 
   function it appears in.)
test.cpp:32: error: parse error before `;' token
test.cpp:35: error: `cout' undeclared (first use this function)
test.cpp:35: error: `endl' undeclared (first use this function)
test.cpp:71: error: `m' undeclared (first use this function)
make: *** [test.o] Error 1

The problem seem related to the standard c++ library available on
hoary-AMD64, I don't understand why there is no definition for "string"
and "list" classes.
I have already try to install all the possible packets available on
hoary but the problem persists.
Can anyone help me ?

Thank you.

Andrea.
