GCC 4.7.2-5 doesn't like implicit conversion of unsigned to signed types

To make rapidjson compile cleanly with our warning flags, I had to make this 
trivial change:

May I know what is your warning flags settings?
After some efforts, the master branch at https://github.com/miloyip/rapidjson 
can be compiled with -Wall -Wextra -Weffc++ -Wswitch-default
Can you verify it in your environment?
Thank you.
