<pre>I think the complaint is about strtol(), which is being used apparently
to find the other end of the numeric value (returned in the char** arg)
while the number is ignored, thus causing this error.
It does seem that nobody is going to "accidentally" ignore the result of
strtol. The warning really should be on functions returning things you
*must* do something with, for instance malloc() where if you don't free
the returned value you have a memory leak.
And they really should restore the (void)fn() work-around, which is
readable.
