It looks like the compiler when compiling 'dcomplex.h' knows about
'complex' template from 'std' namespace, but the file 'dcomplex.h'
is written to assume that "complex" is a class and not a template.

If you do

    #include <complex>
    using namespace std;
    typedef complex DComplex;

you will get the same error (probably) on any conforming compiler
because the use of 'complex' requires the template arguments here:

    typedef complex<double> DComplex;

I don't know how to resolve your problem, without seeing the Rouge
Wave headers and knowing how compiler gets there it's quite hard.

Do you really have to use Rogue Wave?
