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."


2001-08-11  Brendan Kehoe  <brendan@zen.org>

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