Hi everyone,
excuse me to drop in your conversation but ...
i am a user of boost 1.33.1 ... i have size1() and size2() used in all
of my code...which means hundreds of calls...
will it still work once 1.34.0 is released??????
i think this was already a change from 1.32 ... so i hoped it would be
stable now.
thanks in advance
Riccardo
