Bug ID: 57935
           Summary: dmon file watching library doesn't recursively watch
                    existing directories
           Product: Wine
           Version: 10.3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

With the dmon file watching library found at https://github.com/septag/dmon, it
fails to report changes from within subdirectories with the
DMON_WATCHFLAGS_RECURSIVE flag enabled. It only manages to do so with
subdirectories created during the runtime of the program, but directories
present from before the program had started are not watched.

I've tried on Wine versions as far back as 7.5 and the bug is still present,
thus I am not sure if this is a regression or not.

Code to reproduce can be found in the README of the repository, with the only
changes necessary being a printf inside the callback, and a loop to prevent it
from instantly terminating.
