simple program does not compile with g++-4.3 but with g++-4.2

[Emanoil Kotsev]

Hello, I'm trying to learn a bit more of c++. Unfortunately what was working
in g++ 4.2 is not working in 4.3 anymore. Why? I don't think I'm suppose to
be changing my code because of this or knowing what somebody did change in
the compiler. Perhaps I'm missing something like compatibility for 4.3.

I'm using debian stable. Thanks in advance

#include <iostream.h>

int main()
   {
     cout << "The size of an int is:\t\t"    << sizeof(int)    << " bytes
\n";
     cout << "The size of a short int is:\t" << sizeof(short)  << " bytes
\n";
     cout << "The size of a long int is:\t"  << sizeof(long)   << " bytes
\n";
     cout << "The size of a char is:\t\t"    << sizeof(char)   << " bytes
\n";
     cout << "The size of a float is:\t\t"   << sizeof(float)  << " bytes
\n";
     cout << "The size of a double is:\t"    << sizeof(double) << " bytes
\n";

        return 0;
