title: gdb package not appearing in Cygwin setup
body: <p>I need to write some programs in C, so I've downloaded and installed cygwin and Eclipse Neon cpp.
  I've installed the required Cygwin packages and my C programs are compiling and running but I can't debug them because GDB isn't installed.
  I get "Error with command: gdb --version" when I try to debug in Eclipse.
  I've opened the Cygwin setup again, searched but there's no GDB in the packages (<a href="https://i.stack.imgur.com/zKZLz.png" rel="nofollow noreferrer">Picture of the installation</a>) list. How can I add the GDB package to the Cygwin setup and install it so that Eclipse can use it?
  The difference between my question and the one that is suggested is that I entered the setup but can't find the package.
  I'm running Windows 10, Eclipse Neon.1a Release 4.6.1 and Cygwin 2.6.0</p>
  
  <p>Thanks</p>
