Why is misra-17.3 only checked inside if/while condition ?

it was probably to avoid some false positives. But it's not a good heuristic.
We don't assume that cppcheck users provide the include paths for standard headers. And the misra.py addon does not load std.cfg file.

Yeah, I noticed misra addon treated __typeof__ extension as a function and it was only reported when inside if( ) condition.
Loading Gnu.cfg library also was not helping as it misra addon also doesn't know typeof() .
