Also, Vera++ could be useful to fix potential issues such as include 
guards without BOOST in symbols:

#ifndef PROGRAM_OPTIONS_VP_2003_05_19
#define PROGRAM_OPTIONS_VP_2003_05_19

should be

#ifndef BOOST_PROGRAM_OPTIONS_VP_2003_05_19
#define BOOST_PROGRAM_OPTIONS_VP_2003_05_19

allowing the bcp translation to replace it with:

#ifndef MYLIB_BOOST_PROGRAM_OPTIONS_VP_2003_05_19
#define MYLIB_BOOST_PROGRAM_OPTIONS_VP_2003_05_19

which would be much safer in allowing proper side-by-side headers from 
two versions of boost.
