As the summary says, -Wmissing-format-attribute produces false positive
warnings when a function is declared to use a vprintf-like prototype, and this
can't be fixed because the printf attribute does not support varargs functions
(of course).
I'm attaching a testcase that should identify the problem. I hope it's in the
right format, I don't follow development closely, so I just adapted a testcase
from Joseph S. Myers that was added with the fix to bug #1017.
