They are the same.
Initially, I sent all 10 patches out at the same time, but I only saw 5 of them in my mail box. So I re-sent the 5 missing ones. Half hour later, I found the 5 previous missing emails were not lost, and received again at a later time.
The "g_" was used for global variables. I also saw some other global variables with the hungarian notation. Since this notation is not related to camel case conversion, how about we remove the hungarian notations in a separate patch?
Thanks,
