Bug#897865: Code compiles just fine with current commit in Salsa

[Hilko Bengen]

Hi,

greetings from BSP in Karlsruhe.

The current commit in Salsa -- 00b7e79dd144ebfc5d187c331353b50239b032db,
marked "snapd (2.35.5-1) UNRELEASED" -- builds the test code including
locking-test.c just fine, but various tests then fail.

Cheers,
-Hilko
