--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think there's no way to mark Warning options as target specific, 'Target'
isn't a flag, it's the main keyword.

How did you specify 'Target'?  I think that

Wmisspelled-isr
Target C C++ Var(avr_warn_misspelled_isr) Init(1)
Warn if the ISR is misspelled, ...

should eventually work?
