I can relate to your wanting to use -Wno-sign-compare.
The sign-compare warnings can be hard to fix properly --
i.e., without resorting to casts.

I use these for coreutils and for any other project where I have control:

  -O -W -Wall -Wshadow -Wimplicit-int -Wformat-security -fno-common

Of course, pragmatism sometimes dictates turning off a particular
type of warning for individual files, but I haven't had to resort to
that for coreutils.
