This patch set contains various fixes that repair macOS builds for
spice-gtk (and presumably clang builds as a side effect), notably:
- Fixes for clang-specific warnings, notably on alignment
- Addition of macOS detection in configure script
- A couple minor portablity fixes
This requires an update to spice-common, see
https://lists.freedesktop.org/archives/spice-devel/2017-May/037505.html.
The reference to submodule in this patch serie is updated with a
reference that can be fetched from https://github.com/c3d/spice-common.git.
Version 2 takes into account comments by Frediano Ziglio and Pavel Grunt,
specifically:
- Clarify purpose and behavior of macros in patch commit message
- Change one case to 'unaligned'
- Improve way to avoid 'unused variable' warning
Acked by: Christophe Fergeau <cfergeau at redhat.com>
Version 3 takes into account comments made by Christophe Fergeau in
his ack message, specifically:
- Improve the log message description of SPICE_(UN)ALIGNED_CAST.
Hopefully the new one is better.
- Make spaces after commas consistent
In addition, v3 re-enables ucontext on macOS, following comments
that this is the right thing to do for performance. This required the
elimination of one more alignment warning.
Version 4 takes into account comments made by Pavel and Frediano,
specifically:
- Reorder the previous iteration to group things more logically
- Add a TODO comment for macOS in set_mouse_accel
Version 5 adds the --enable-alignment-checks configuration option
and disables all runtime checks by default.
Version 6 groups the --enable-alignment-checks configuration option
with the warning detection, and addresses some of the alignment issues
as discussed with Frediano.
Version 7 modifies some comments (nits reported by Christophe Fergeau),
fixes a bogus array size change I had made earlier (seen by Frediano Ziglio),
and takes into account one additional cast introduced in master lately.
Version 8 separates a whitespace change in its own patch, groups
alignment detection and alignment fixes in a single patch, and
changes the type of palette to guint32, all suggested by Frediano.
For reviewers convenience, the diff between v8 and v7 is:

Remove trailing space

Avoid clang warnings on casts with stricter alignment requirements
Remove warning about unused variable when building on macOS
