[PING] Re: [PATCH, i386] Fix some warnings/errors that appear when enabling -Wnarrowing when building gcc

[Eric Gallager <egall@gwmail.gwu.edu>]

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.
