I installed tangobos, but I cannot seem to mix tango/phobos.

Takker!
It works like a charm, I only wish I had found dwin 5 hours earlier :)

I seem to recall those are the kinds of errors you run into when you
define constants in an extern(Windows) block as "const" instead of
using an enum.  The problem is that extern(Windows) things don't get
mangled with their package name, so if you have the same constant in
two places you will get a clash.  Enums doing use storage, though, so
they don't clash.  Maybe that will help you get to the root of the
problem.

But then I cannot see how anyone including stdlib is able to compile.
Shouldn't both tangobos and tango change these to enums then?

Then problem is when you try to link two libraries and both of them 
define the same constant, and they do it like this:

extern (C) const int EXIT_SUCCESS = 0;

Which results in both compiling to the symbol _EXIT_SUCCESS.  There's no 
point in using extern (C) with those constants, but both phobos and 
tango do it anyway, which causes trouble with tangobos.  Some of them 
are changed to enums now, but apparently not all.

When I was using tangobos, I just commented out the duplicate 
definitions in tangobos.  Or you can prefix them with extern (D), I 
guess. Or make them enums.
