Bug#171561: g++-3.2: iostream does not work

[Francesco Potorti` <pot@gnu.org>]

Package: g++-3.2
Version: 1:3.2.1-0pre3
Severity: normal

Sorry if this is not a bug, but I cannot find any way why it isn't.  I
cannot make iostream work.  The appended short program compiles (and
works) okay with g++-2.95, but does not compile with either 3.0 or 3.2
(against which this report is sent).  The error messages are:

g++-3.2 bin2a.cc -o bin2a
bin2a.cc: In function `int main(int, char**)':
bin2a.cc:9: `cerr' undeclared (first use this function)
bin2a.cc:9: (Each undeclared identifier is reported only once for each function 
   it appears in.)
bin2a.cc:10: `ifstream' undeclared (first use this function)
bin2a.cc:10: parse error before `(' token
bin2a.cc:12: `f' undeclared (first use this function)
bin2a.cc:13: `cout' undeclared (first use this function)
make: *** [bin2a] Error 1
