Subject: [PATCH 2/2] ci: Add a warning check for 32 bit builds.

We already compile and test 32 bit builds, but warnings don't turn
anything red unless something actually breaks at runtime.  Add a new
command to the CompileWarnings task for that, so that such breakage is
less likely to make it to the build farm to be caught by "adder".
