And even for persons usually very healthy, flu can occasionally lead to either direct viral or secondary bacterial pneumonia. An obvious warning sign is if the person starts to have trouble breathing. That is zen simplicity itself.
A non-obvious sign which I think it potentially very helpful is this:

New York Times, Denise Grady,

In children without chronic health problems, it is a warning sign if they seem to recover from the flu but then relapse with a high fever, Dr. Frieden said. The relapse may be bacterial pneumonia, which must be treated with antibiotics. . . "
And presumably for adults, too.
The World Health Organization, also from 2009, recommends both antivirals (such as Tamiflu) and antibiotics for suspected cases of flu-caused pneumonia. Apparently, it's often hard to tell whether it's viral or bacterial.

Now personally, I think it would be worth getting in and seeing a doctor or having a doctor call in prescription(s) and starting those prescriptions in like three hours. Doesn't mean that a relapse with high fever is pneumonia, but it might be. And hopefully the phrase "possible pneumonia" will work even better than a swear word in getting the doctor on the phone!
