[boost] Bug fix for BCP

Evidently I either don't have access to the Boost CVS repository on SourceForge or I still can't figure out how to use CVS, so here is a fix to a serious problem with John Maddock's BCP program, and someone else can make the fix. In bcp_imp.cpp, line 17 needs to be changed from: : m_list_mode(false), m_cvs_mode(false), m_unix_lines(false), m_scan_mode(false) to : m_list_mode(false), m_licence_mode(false), m_cvs_mode(false), m_unix_lines(false), m_scan_mode(false)
