`watchdog_fsevents.c`: possible to implement a fallback code for < 10.7?

[Sergey Fedorov]

There is an interest from Mac users to have maestral on older systems, I thought to add a port for it, however it requires watchdog, which is presently broken on those systems due to usage of unsupported functionality in watchdog_fsevents.c: https://trac.macports.org/ticket/64584

Is it possible to have a fallback?

[Mickaël Schoentgen]

What you are asking is a good amount of code for an already complexe beast. Moreover, it would be for a small amount of users.

I won't add compatibility code to FSEvents.

You can stick with a version before 1.0.2 where the support for macOS 10.7 was removed. And even before that, I am not sure it worked for macOS <10.7.

Have a try with older versions, you might have some results.

@BoboTiG Thank you for the reference to a specific version, it is helpful. And yes, I do understand that maintaining a huge amount of code is a burden.

P. S. 1.0.1 still fails on 10.6, but I will try to find the latest that works and see if it passes tests.

@BoboTiG So 0.10.3 installs (after removing one flag unsupported by gcc), and apparently works:
