Ping? CC-ing an i386 maintainer since the patch mostly touches i386-specific files. Also, to clarify, I say "warnings/errors" because they start off as warnings in stage 1 but then become errors in stage 2. Note also that my patch leaves out the part where I modify the configure script to enable -Wnarrowing, because the rest of the code isn't quite ready for that yet.
