I don't hink -Winline does anything useful for C++ code.

-Winline means emit a warning if something was declared with the inline 
keyword, but was not inlined by the compiler.  For C code, where inline 
tends to be used sparingly, and only for functions that are likely to be 
inlined, this warning may give you useful info.  For C++ code, where 
inline tends to be used a lot, and some things are implicitly inline, 
this warning will  just give you a lot of noise.
