Hallo, when trying to build up a configuration for the new Borland BCB 2006 compiler I got an error message complaining about line 49 in file boost/iostreams/positioning.hpp: inline stream_offset fpos_t_to_offset(fpos_t pos) ^^^^^^ Shouldn't the above read std::fpos_t ? This solves the problem for my compiler. Cheers, Nicola Musatti
