Description:
------------
bcadd("-0.0", "-0.0", 1); // returns -0.0
bccomp("-0.0", "0", 1); // returns -1
I believe that the first expression should return '0.0',
and the second one should return 0.
The second expression implies that "-0.0" is mathematically less than
"0", which is incorrect.

I also submitted another bug related to minus zero.
echo -0.1 * 0; // returns -0
--
Reproduce code:
---------------
<?php
echo bcadd("-0.0", "-0.0", 1) . "<br>\n"; // returns -0.0
echo bccomp("-0.0", "0", 1) . "<br>\n"; // returns -1
?>
Expected result:
----------------
-0.0
-1
Actual result:
--------------
0.0
0
