GCC 4.0.1 - iostream: No such file or dir....

[Chris Garrett <cgarrett@degarrah.com>]

I finally got 4.0.1 built in msys. I must have screwed up my msys/gcc 
setup because a clean install of msys and gcc-3.4.1 worked. I started 
with a simple test:

main.cpp:
~~~~~~~~~~~~~~~~~~~~~~~~~~
#include <iostream>

int main()
{
        cout << "Hello\n";
        return 0;
}


then I try and build it:
~~~~~~~~~~~~~~~~~~~~~~~~~~
chris@NEPTUNE /d/tmp/simple$ g++ main.cpp -o main
main.cpp:1:20: error: iostream: No such file or directory
main.cpp: In function 'int main()':
main.cpp:5: error: 'cout' was not declared in this scope

I looked thru in /mingw/include/c++/4.0.1 and iostream exists in that 
directory. Is there something I'm missing? Do you need to specify gcc's 
include directories explicitly now?

Thank you

Chris
