In bash you need to export the variable.  Plus, the value you're using is
wrong.  Try

  export DISPLAY=localhost:0.0

and then start ddd.

This one's my fault.  Basically, XFree86-base is an empty package,
therefore no manifest (file list) is generated for it.  Cygcheck doesn't
find this package, so it complains (as you'll see if you pass the "-v"
flag to cygcheck).  When I wrote that part, I thought the missing file
list is an abnormal situation.  Turns out I was wrong.

In other words, please ignore this status for the XFree86-base package.
I'll try to get a fix for this into the next Cygwin release.
