Last I checked, boost::program_options took const char* in several
places where it would end up storing them as std::strings anyway. Taking
"const std::string&" would also clarify that passing temporary strings
is fine, whereas "const char*" as an arg hints to me that the pointers
should remain valid until options_description is destroyed (purely
question of taste though).
I'd vote to replace const char* everywhere in the program options
interface with std::string. (excluding the "char* argv" of course)
