11It’s possible that the variables here are only marked as volatile
12because they’re arguments to `g_once_*()`. Those arguments will be
13modified in a subsequent commit.

5 macro variables
6MIME-Version: 1.0

8Content-Transfer-Encoding: 8bit

10It’s not necessary and provides no thread safety guarantees.
11
12The `volatile` qualifiers on the function arguments have to be kept, as
13they are (unfortunately) part of the API.

6This is technically an API break, but since the type is meant to be
7opaque (third party code is not meant to treat it like an integer) it
8should not cause problems.

9`volatile` should not be used to indicate atomic variables, and we
10shouldn’t encourage its use. Keep the tests, since they check that we
11don’t emit warnings when built against incorrect old code which uses
12`volatile`. But add a comment to stop copy/paste use of `volatile`
13in the future.

9
10In the Windows destructor list, consistently access
11`g_private_destructors` using atomic primitives.
12
13`g_atomic_pointer_compare_and_exchange()` should be equivalent to
14`InterlockedCompareExchangePointer()`, but is a bit more understandable
15in a general GLib context, and pairs with `g_atomic_pointer_get()`. (I
16can’t find a Windows API equivalent for that.)

5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9Half of the references to `init_state` in `gtype.c` already correctly
10accessed it atomically, but a couple didn’t. Drop the `volatile`
11qualifier from its declaration, as that’s not necessary for atomic
12access.
13
14Note that this is the `init_state` in `TypeData`, *not* the `init_state`
15in `IFaceEntry`.
