Subject:	new Win98 install -- can't resolve std::cout

I apologize for such a basic question. I've installed binaries for gcc ports to
Windows several times in past few years and I've always had the whole
system come up easily.

Yesterday I used the new setup.exe program to install all the packages on
a Windows98 system. Installation went fine, bash came up quite happy.
I tried a "hello world" program called test.cpp, which looks like this:

>tango AT TETONS /cygdrive/n/randy/qprofile
>$ cat test.cpp
>
>#include <iostream>
>
>int main()
>{
>        std::cout << "Hello world!" << std::endl;
>}

Then I ran the command "gcc -ansi -v test.cpp" and got link errors. The screen
dump looks like this (forgive the screen wrapping -- I copied-n-pasted this
from the bash window):

$ gcc -ansi -v test.cpp

So, what went wrong? It looks like all the likely libraries were specified in the
link phase. It doesn't matter if I use the -ansi switch or not. It also doesn't matter
if I include <iostream.h> and use cout in the global namespace. Same link error.

A C++ "hello world" program that uses <stdio.h> and printf() links correctly.
It links against the identical set of libraries.

Suggestions?

Thanks!
