In version 5.1.3 and earlier, you could write
(define-cstruct _git_index_entry_unmerged
([mode0 _uint]
[mode1 _uint]
[mode2 _uint]
[oid0 _git_oid] ; assuming _git_oid is defined
[oid1 _git_oid]
[oid2 _git_oid]
[path _string]))
With the latest development version (or v5.1.3.3 and later), you can
write
(define-cstruct _git_index_entry_unmerged
([mode (_array _uint 3)]
[oid (_array _git_oid 3)] ; assuming _git_oid is defined
[path _string]))
