gcc, installation & compiling within cywin structure

Hello - I'm not sure if this forum is the correct place to pose this problem:

I have a recent installation of cygwin running under win-7.  I am trying to build another package into the installed octave, so am working on getting the gcc compiler running.  In trying to build the standard hello.cpp, I'm getting the following results:

$ g++ hello.cpp
/usr/lib/gcc/i686-pc-cygwin/4.7.3/../../../../i686-pc-cygwin/bin/ld: cannot find -ladvapi32
/usr/lib/gcc/i686-pc-cygwin/4.7.3/../../../../i686-pc-cygwin/bin/ld: cannot find -lshell32
/usr/lib/gcc/i686-pc-cygwin/4.7.3/../../../../i686-pc-cygwin/bin/ld: cannot find -luser32
/usr/lib/gcc/i686-pc-cygwin/4.7.3/../../../../i686-pc-cygwin/bin/ld: cannot find -lkernel32
collect2: error: ld returned 1 exit status

where hello.cpp is the standard sort of thing:

#include <iostream>
using namespace std ;

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

I can't build the "c" version of the same program, get the same results.

There's nothing in usr/local/bin,  usr/local/include, usr/local/lib, they're empty directories.  This is odd.

I've set library paths:

export LD_LIBRARY_PATH=/lib
export LIBRARY_PATH=/lib
export CPATH=/usr/include
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS

/lib and /usr/include are populated with what looks to be like a reasonable set of directories, but I really don't know for sure.

I've been able to compile on my system (mingw under windows) but I can't get gcc running under cygwin.

I'm out of my water at this point and fumbling around.  The tutorials and tfm that I've found don't seem to cover what I have going on here.  Any advice?

thanks - Mark Sheffield
