Wow, thanks for the research! Much appreciated. I think you're right - the 0 argument is telling. I guess the next step is to explicitly call out the -W options excluding empty_body that -Wextra turns on. Like: 


-Wclobbered
-Wignored-qualifiers
-Wmissing-field-initializers
-Wmissing-parameter-type
-Wold-style-declaration
-Woverride-init
-Wsign-compare
-Wtype-limits
-Wuninitialized
-Wunused-parameter
-Wunused-but-set-parameter

I tried the above options. LOL - 7 of these aren't recognized! Oh well.

Thanks again,

Bill
