Expected Behavior

Should have compiled OK (0.15.2 compiles OK)

Library version, just in case it is relevant: libsystemd-dev/noble-updates,now 255.4-1ubuntu8.11 amd64

Fixed in ziglang/translate-c@88164c4, upstreamed in #25780

It does then hit ziglang/translate-c#92 but that can be worked around by with

translator.defineCMacro("_SD_BEGIN_DECLARATIONS", "");
translator.defineCMacro("_SD_END_DECLARATIONS", "");
