Re: No warning for unused variables?

[LachlanA]

Rik,

The reason gcc doesn't warn about unused classes is probably that calling
the constructor itself may be a "use" if it has side effects.

If noone reports a tool, you could try one of these:

(Really ugly)  #define the class name(s) to "int", and grep through the
(huge number of) resulting errors for "unused variable".  I know it's
ugly...

(Some effort, you could delegate :) write something to count the number of
identical strings of [a-zA-Z_0-9] within each pair of { }, and check when
the number is 1.
