How many extra warnings do you get by adding these flags (e.g., just by doing 'export CFLAGS= ...' before building)? It might be useful to see a sampling of those warnings. The addition of these flags should be conditional on gcc's version being >= 4.3: gcc 4.2 apparently has a different meaning for -Wconversion (to do with implicit conversions when passing function arguments), and generates crazy numbers of warnings on my OS X 10.6 machine (which comes with gcc 4.2). Why '-Wno-sign-conversion'? Is fixing all the places that have implicit sign conversions a reasonable goal, or are there just too many of those?
