No warnings for this particular test.

I have now tested with GCC 4.6.3 (by exporting CC="x86_64-pc-linux-gnu-gcc-4.6.3" and CXX="x86_64-pc-linux-gnu-g++-4.6.3")
and builtin_abs.__test__.int_abs tests pass with GCC 4.6.3.

Result with GCC 4.7.2 after applying your patch:

======================================================================
FAIL: int_abs (line 35) (builtin_abs.__test__)
Doctest: builtin_abs.__test__.int_abs (line 35)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib64/python2.7/doctest.py", line 2201, in runTest
    raise self.failureException(self.format_failure(new.getvalue()))
AssertionError: Failed doctest test for builtin_abs.__test__.int_abs (line 35)
  File "/tmp/Cython-0.18b1/BUILD/run/c/builtin_abs/builtin_abs.so", line unknown line number, in int_abs (line 35)

----------------------------------------------------------------------
File "/tmp/Cython-0.18b1/BUILD/run/c/builtin_abs/builtin_abs.so", line ?, in builtin_abs.__test__.int_abs (line 35)
Failed example:
    int_abs(-max_int-1) == abs(-max_int-1)   or (max_int, int_abs(-max_int-1), abs(-max_int-1))
Expected:
    True
Got:
    (2147483647, 18446744071562067968L, 2147483648)
