Re: [Vala] Strangeness with sorting using Gee ArrayList

[Christer <christer nissen gmail com>]

Hi again,

Sorry, I noticed I accidently included compiler warnings that are not
relevant. They occur because this test case code is part of the real project
Im building. So only these are relevant to this test case:

COMPILER WARNINGS
==================
Test.vala.c: In function ‘file2_gee_comparable_
> interface_init’:
> Test.vala.c:323:20: warning: assignment from incompatible pointer type
> <b>Process return 0  execution time: 1.42 s</b>
