State-Changed-Why:
    User error. You are trying nonsense and getting nonsense. No
    surprise.
    
    Had you used a static_cast instead of the C-style cast like
    this:
       f2( static_cast<CAST (*)(int)>(&f1), 4 );
    then the compiler would tell you quite correctly:
    tmp/g> /home/bangerth/bin/gcc-3.3x-pre/bin/c++ x.cc
    x.cc: In function `int main()':
    x.cc:18: error: invalid static_cast from type `int (*)(int)' to type `
       std::complex<double> (*)(int)'
