I believe Brian D. was making the point that the 4.x gcc and friends aren't
officially packaged yet so asking this list about what dependencies there
are for things you've built yourself or downloaded from other sites isn't
on-topic here.  Once this is part of the Cygwin distribution, you shouldn't
need to care what packages are a prerequisite for another, since the
packaging will define those dependencies and 'setup.exe' will honor those
requirements (assuming the user doesn't override them).
