Looks like the intel compiler has a bug with ADL. You can work around 
it by changing the definition of cmplx to this:
template
  struct cmplx ...
Note the extra Dummy template parameter, which will cause ADL to find 
the operators defined in Proto's namespace.
Perfect as usual :) This did the trick. I'll propagate this fix to all 
my terminal entity then.
Should I report this to Intel bug system however ?
You should, if you (or someone) can confirm it happens on Intel 11.0 
also. Here is a simple repro:

namespace N
{
     struct S {};
     template
     void operator+(T const &, U const &) {}
}

template<class T> struct X {};
struct Y : X {};

int main()
{
     Y y;
     y+y;
}

The above code compiles with gcc but doesn't with Intel 10.1
