I've a problem switching from V1 to V2 using complex numbers. With V1 I've used
#include<complex.h> and data-type 'complex', but compiling this programs with
V2 gives errors, so I switched to #include<_complex.h> and the Complex-class.
Now all the inlined operators (+,-,*,...) work fine but all divisions gives
errors while linking, see the example below.

I've tried some libraries, but without success. So which library do I have
to link using the Complex-class?

Thanks for any help,
  Roland

---------------------- file test.cc -------------------------------------
#include <stdio.h>
#include <_complex.h>

int main(int argc, char *argv[])
{
  Complex x(1.0,2.0);
  Complex y(2.0,0.0);
  x/=y;
  printf("re:%f im:%f\n",real(x),imag(x));
}
-------------------------------------------------------------------------
gcc -Wall -O2   -m486  test.cc -o test

test.cc: In function `int main(int, char **)':
test.cc:5: warning: unused parameter `int argc'
test.cc:5: warning: unused parameter `char ** argv'
