These occur when building with GCC 12.1.
It might be the case that these would be suppressed by updating the
package, but that would also require installing new build tools (meson),
as well as potentially more dependencies (wayland).
```bash
In function 'ExprCreateBoolean',
inlined from 'BoolVarCreate' at src/xkbcomp/ast-build.c:316:19:
src/xkbcomp/ast-build.c:119:23: error: array subscript 'ExprDef[0]' is partly outside array bounds of 'unsigned char[32]' [-Werror=array-bounds]
119 | expr->boolean.set = set;

```
Boost conatiner_hash (included via functional -> multi_index) uses
std::unary_function, which was deprecated in C++11, and "removed" in
C++17. It's use causes wanrings with newer compilers, i.e GCC 12.1.
```bash

use.

I've also played with updating the libxkbcommon package, which requires changing build systems (meson/ninja), there's a work in progress branch here, fanquake@adb123d, but it doesn't yet work properly. If someone wanted to play with that, they could, but I also don't think we should block building depends with GCC 12 on updating libxkbcommon. |

This is fine imo. I mean we only use libxkbcommon to link against, it doesn't really matter what the version is (older is better, probably, from a compat point of view). |
