Hmmm... you're using a *very* old compiler version!  Anyway, I found the 
following in my Borland archive, in "Include\complex.h":

  template <class T>
  inline T abs (const complex<T>& a) { return 
(_RWSTD_C_SCOPE_SQRT(norm(a))); }

(From the Standard C++ Library by Rogue Wave Software, delivered with 
Borland C++ v5.5.)
