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

I just rebuilt emacs-24.4 tag from git while glib 2.40.00 is installed. But
the same results; gfilenotify doesn't work this time. The last time it
worked, it was the same RHEL 5.10, glib 2.40.00 and emacs 24.4. Here is the
config.h (renamed) created for the 24.4 build:
https://dl.dropboxusercontent.com/u/10985/config-emacs-24.4.h

Is there anything else that gfilenotify depends on? Can I test something
from the terminal to verify glib installation that would make gfilenotify
work?

Thanks!
