libgmp-10.dll is missing

I recently installed MinGW on my 64-bit Windows 7 computer and when I attempt to compile the most basic of c++ programs, for example

#include<iostream>

using namespace std;

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

I get the error that "The program can't start because libgmp-10.dll is missing from your computer."

Have you tried adding C:\MinGW\bin as a System variable Path (not PATH) in Settings->System Properties->Environment Variables?

I saw this solution on this page: Missing libgmp-10.dll

Go to the mingw download page and browse the following directories:

MinGW / Base / gmp / gmp-5.0.1-1

Currently you end up with the following link:
http://sourceforge.net/projects/mingw/files/MinGW/Base/gmp/gmp-5.0.1-1/libgmp-5.0.1-1-mingw32-dll-10.tar.lzma/download
and it contains the needed file.

I know there are automated methods for installing mingw gcc, but when one uses single mingw packages, then gmp is one of obligatory downloads.
