Because that is an improved version of the checker. The current form is not 
testable because it detects too less functions. To have more results functions 
were added that may return NULL on error and a missing comparison to NULL is 
detected (similar as missing comparison to `EOF` in this patch). (To have the 
check for NULL some other improvements were made.) The '???' is part of 
development of note tags, the name of the called function is to be placed there 
(probably there is better way of doing these reports).
