>Description:
testing an assignment of pointer to member
functions is a test of the return value of
the member function, and not the function
pointer itself. Compiling such code with
-ansi results in warning, NULL used in
arithmetic in example code below.
>How-To-Repeat:
Compile isolated example supplied. g++ -Wall -pedantic -ansi q.cc -o q
See warning:
q.cc: In method `Wik::Wik ()':
q.cc:11: warning: NULL used in arithmetic
>Fix:
No suggestions.
