iomanip should be in djgpp/lang/cxx with the other C++ header files.

*Please* when you report a problem make the effort to post the full
source code to the smallest program that demonstrates the problem,
together with the exact command line you use to compile and the full
errors the compiler issues.  That way others will be happy to make the
effort to find you a solution.

I think this might do what you want:

    cout.setf(ios::fixed, ios::floatfield);
    cout << area << endl;

Most likely this feature has not yet been implemented in GCC.
