Original issue reported on code.google.com by yuriv...@gmail.com on 1 Jul 2014 at 9:28

The first one -Wunused-local-typedefs should have been fixed in 

https://github.com/miloyip/rapidjson/commit/1eb62770d33ed00a4ba1d5048b616e4831ee
603a

For the second one -Wempty-body,

I cannot reproduce it in gcc 4.8.x, can you propose a fix method?

For example, 

if (!level->inArray && level->valueCount % 2 == 0)
    RAPIDJSON_ASSERT(type == kStringType);  // if it's in object, then even number should be a name

change to 

if (!level->inArray && level->valueCount % 2 == 0) {
    RAPIDJSON_ASSERT(type == kStringType);  // if it's in object, then even number 
    (void)type;
}

Will this work?

Besides, please note that the repository has been moved to 
https://github.com/miloyip/rapidjson/
