It's 100% unrelated.

First of all, you just look at the value of flymake-diagnostic-functions.

Apparently, c++-mode uses flymake-cc.

You might want to go ahead and read it, but it's a minimalistic solution 
that relies on Make and a particular target being present (see 
flymake-cc-use-special-make-target). Would I be correct in assuming that 
you don't have it?

Flycheck probably has more sophisticated checkers, but the new Flymake 
API is not too hard. You should be able to port whatever checker you 
have been using to Flymake without too much difficulty.
