Hi~

I met build warnings about 'comparison between signed and unsigned integer expressions' on building webkit efl port.

Ok~ I'll fix this and also about the below.
+    for (uint32_t i = 0; i < exec->argumentCount(); i++)
(The return type of ExecState::argumentCount() is size_t)

Thanks for the comment.
