In CVS boost/iostreams/filter/zlib.hpp, revision 1.21 there is:

g++ -Wall -W (correctly) states: .../boost/iostreams/filter/zlib.hpp:120: warning: unused parameter 'calculate_crc'
Normally I wouldn't worry about trivial warnings, but in this case the argument is being ignored when initialising the member data which looks a bit odd to me...
this->calculate_crc is being initialized with zlib::default_crc and not the ctor argument.
