Using "asm" in a C++ interrupt handler (the CLASS_IRQ macro) produces the
"misspelled signal handler" warning for every AVR interrupt routine. Thus it
would be fatal to using this method if detecting this aborted the compile.
So any change would need to keep the C++ situation in mind, meaning the
action following the detection of a misspelled handler would need to
discriminate between C and C++ code. 

A lot of bother and hence my suggestion for some means for turning it off,
typically after one has got all the interrupts in a project working.
