I wanted to get rid of all old-style casts in my application, so I turned on -Wold-style-cast in gcc and found a whole bunch of old-style casts in boost headers. It seems to me that the boost coding style guidelines ought to explicitly discourage old-style casts. Any one else have a point of view? I've attached a list of the old-style casts gcc found in the 1.36 headers. This list isn't exhaustive, since my app doesn't use all boost libraries. :) -- Jon Biggar jon@floorboard.com jon@biggar.org jonbiggar@gmail.com ../../../boost/asio/detail/posix_fd_set_adapter.hpp:41:
