compiler error

[brown]

When I compile src/diff.c I get an error for the following code in Diff_getitem:

if (PyLong_Check(value) < 0)
    return NULL;

Apparently PyLong_Check returns a boolean, which can never be negative,
so the test will never succeed.

There are not boolean values in C, PyLong_Check returns an int, check
https://docs.python.org/2/c-api/long.html#c.PyLong_Check

Please post the error.

Here is the compiler error message. PyLong_Check returns
0 or 1 so the comparison is always false.

third_party/py/pygit2/src/diff.c:485:29: error: comparison of constant 0
with boolean expression is always false
