The problem is that with or without the external preprocessing of source/header files enabled via '-p', the error message remains the same as if the '-p' option didn't actually cause CINT's preprocessing to defer to 'g++ -E'.

$ root -p || root
root [0] #include <boost/format.hpp>
Error: G__getvariable: expression  FILE:/usr/include/boost/config.hpp LINE:23
...
Limitation: can not handle macro BOOST_USER_CONFIG <boost/config/user.hpp> Use +P or -p option FILE:/usr/include/boost/config.hpp LINE:23

Thanks, that looks promising.  I shall.
