I don't like to force the compiler to behave in a way that is not
standard compliant.  Or do you mean to force the compiler to
actually inline all inline functions?  This is impossible for
virtual functions.

This is dangerous, since it may suppress real diagnostics, but at least
it is unlikely to break correct code.

This can violate the ODR.  It is out of the question as far as I am 
concerned.

The linker ought not to be issuing a warning.  I don't suppose there's a
way to make it shut up without also suppressing legitimate warnings, is 
there?
