Undeclared name 'Auto_Cast' for type 'Field_Flag'

I'm getting a compilation error when trying to build from source:

/home/ptrschneider/distrobox/odin/.src/ols/src/server/analysis.odin(711:7) Error: Undeclared name 'Auto_Cast' for type 'Field_Flag'
        if .Auto_Cast in flags {
            ^~~~~~~~^
/home/ptrschneider/distrobox/odin/.src/ols/src/odin/printer/visit.odin(2606:6) Error: Undeclared name 'Auto_Cast' for type 'Field_Flag'
        if .Auto_Cast in flags {
            ^~~~~~~~^

Environment:

OS: Archlinux distrobox inside WSL (Ubuntu 22.04). I know it's an unusual setup, but the error message doesn't seem to be related to the setup.
odin version dev-2023-09:2aa3cabd8, from AUR package odin-git

Tried to install the language server both from source, and from the AUR package odinls, both gave the same error as a result.
