 Hi,
 
 Please apply following patch to mainline, which addresses PR 4543.
 
 "Library DR #79 resolved that the second argument to polar should 
  be a default argument initialized to 0. Otherwise, calls to
  polar with only one argument will result in complaints that 
  there is no available candidate."

 	* include/bits/std_complex.h:
 	  Default initialize second argument of polar to 0, as
 	  specified in Library DR #79
