Proposed patch
The incomplete dependency output causes issues with recc¹ with at least one
project² that has multiple identical header files (dummy files that are
practically empty except for `#pragma once`).
The attached patch fixes the issue by also comparing `st_dev` and `st_ino` in
addition to `st_mtime` and contents. This seems like a simple improvement to me
and shouldn't change the behavior with regards to symlinks and hardlinks.
Is this something that may be acceptable or can anyone think of a reason right
away why this would not be the right solution? I've tested it manually but
haven't run the testsuite yet.
