Test failure under Windows 8

[Luchau]

When I run the test suite under Windows I get this failure :

======================================================================
FAIL: test_overflow (test_representation.RepresentationTestCase)
We use a finite buffer (typically, 2048 chars) to construct the repr
----------------------------------------------------------------------
Traceback (most recent call last):
  File "C:\Users\Lucas\Python\PyPoly\tests\test_representation.py", line 47, in
test_overflow
    self.assertEqual(len(long_repr), 2047)
AssertionError: 2048 != 2047

----------------------------------------------------------------------

Ok I eventually got it: this is because of a specific behavior of the snprintf function on Windows platforms...
