[Message part 1 (text/plain, inline)]

Thanks. glib looks like the culprit.

When filenotify used to work, I had glib 2.40.00 installed on RHEL 5.10.

Then I upgraded to glib 2.44.00 last week (also rebuilt emacs after that)
in efforts to fix a frame issue I am still facing (
http://emacs.stackexchange.com/q/10745/115 ). The upgrade didn't fix that
issue and it seemed that it didn't break anything so I stayed at that
version.

But looks that that broke the gfilenotify functionality.

Now, I did make uninstall on glib 2.44.00 and reinstalled glib 2.40.00 and
rebuilt latest emacs from master. But that did not fix the gfilenotify
issue. I don't know what else I can look into.

Here is the requested src/config.h after reverting back to glib 2.40.00 and
rebuilding emacs from master:

Thanks for the help!
