Would the attached help ?

template <class T> inline void no_unused_variable_warning(const T&) {}

(there was subsequent discussion about the name but general approval as a
'Boost's Good Way of Doing It')

attached mail follows:

Dear Boosters,

Did the one change Dave suggested of using the function template solution
instead of the macro.. To avoid yet another BOOST macro...

template <class T> inline void no_unused_variable_warning(const T&) {}

Please take a look at the updated archive:

http://groups.yahoo.com/group/boost/files/disable_warning.zip

..and attached, as it's very small.

Enjoy.
