...I guess those guys hunting for broken busyloops in the other thread 
could also benefit from similar searching commands introduced in this

...Hmm, I plugged in "a preprocessor" too to manage with non compliant 
coding styles :-). Please understand that the line numbers are not an 
exact match due to preprocessor changes:

$ for i in `find . -name '*.[ch]'`; do echo $i; indent -npro -kr -i8 -ts8 
-sob -l8000 -ss -ncs -cp1 -nhnl -st $i | egrep -n "[[:space:]]if [(].*[)] ;$";
done | grep -B1 "^[^.]"

...some of these are false positives due to constructs like this (not 
sure if there's some better alternative):

if (!ptr)
	;
else if (ptr->something)
	do_it();
else
	do_other();

...plus there might be some #ifdefs in that construct too.
