| I imagine

|   BOOST_MESSAGE("i = "<< makeManip(flog)( setw(5) ) << i  );

doesn't seem to work, (needs another  makeManip *operator(int)?) 
but you are right in your expectation that

| Actually, I am prone to expect that, e.g.,
| plain setw(n) works without anything extra

because

BOOST_MESSAGE("i = "
  << setw(15)
  << makeManip(flog)(showbase)
  << makeManip(flog)(uppercase)
  << makeManip(flog)(hex)
  << i );

works as we would expect

// i =             0XF

and also

        double d = 12.3456789;
        BOOST_MESSAGE("d = " << setw(15) << setprecision(4) << d );
// d =           12.35

So is this the price we pay for writing endl rather than endl()?

(without your cleverer proposal)

Many thanks.
