Maybe, but grep version 2.5.4 will show most of them.

$ grep-2.5.4 -rP --include=*.[ch] "return;\n}" *
[...]

Fixing them has to make sure that there's no
label before the close brace.

gcc has to have a statement before the close brace
of a void return after a label.

label:
}

must be:

label:
	;
}

to compile.
