Subject:	C++ Link Error

I am experiencing a link error with C++ on Cygwin.  I have boiled it down to
a simple test case.  As far as I know I have every Cygwin package installed.
But I have been upgrading this installation for quite some time.

If I take a simple test.cpp file:

=================================
#include <iostream>

using std::cout;

main()
{
	cout << "Test\n";
	return 0;
}
=================================

And run g++, g++ (GCC) 3.2 20020927 (prerelease), against it.  I get the
following:

$ g++ -o test test.cpp -lstdc++
/e/DOCUME~1/rdparker/LOCALS~1/Temp/ccWlq6qX.o(.text+0x27):test.cpp:
undefined reference to `_STL::cout'
/e/DOCUME~1/rdparker/LOCALS~1/Temp/ccWlq6qX.o(.text+0x5d):test.cpp:

eck_exception_maskEv+0x1d):test.cpp: undefined reference to
`_STL::ios_base::_M_throw_failure()'
collect2: ld returned 1 exit status

Having '-lstdc++' on the end or not doesn't seem to matter.
