Just in case you did not realize, casting the return away with
(void) will not squelch this out of the compiler:
builtin/checkout.c: In function 'prepare_linked_checkout':
builtin/checkout.c:947:3: error: ignoring return value of 'link', declared
with attribute warn_unused_result [-Werror=unused-result]
It still feels fishy to see "we attempt to link but we do not care
if it works or not" to me, with or without the "unused result"
issue.
