Congratulations to the birth of your son! I *really* appreciate that you are
still finding the time to do the cleanup work.

Boost.Python appears to be in quite good shape, but I am getting this error:

% cxx -std strict_ansi -msg_display_number -msg_disable 186,450,1115 -tlocal

It is because bad_numeric_cast is now defined as
boost::numeric::bad_numeric_cast instead of boost::bad_numeric_cast. This
simple patch fixes the problem:

OK to commit?
