To me, these look like they should be warnings, not errors, and
looking at the compiler command line it specifies `/warnaserror+`
(which turns warnings into errors). If you look in
Microsoft.Dynamic.csproj (and all other IronPython csproj, by the
looks of it), it specifies:

    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>

which, while well intentioned, is a hindrance when trying to get
things to just compile. I would try setting that to

    <TreatWarningsAsErrors>false</TreatWarningsAsErrors>

and see if you can get any further.
