Thanks for the additional analysis, it makes more sense.

However, how is this related to "newer gcc" then? If the code uses
CLOCK_MONOTONIC, without including <time.h>, it's going to fail
regardless of the gcc version.

Did you test a build with an older gcc (13.x is still supported for
example) ? I assume it will also fail to build without your patch,
meaning that the problem is not gcc version related.

Thanks!
