Just for completeness I want to report other details.

I have tried the test case in (*), more precisely this:

$ gcc -DTRY1 -Wall -o test-dialog3-try1 test-dialog3.c `pkg-config 
--cflags --libs gtk+-2.0`

$ ./test-dialog3-try1
Using gtk_file_chooser_dialog_new.
Done.
Please make sure the FAM daemon is not running before testing again.
(i.e. kill the gam_server process or wait until it is gone)


Now, as you can see, it says "...kill the gam_server process or wait 
until it is gone". Indeed 'ps' shows that gam_server process is still 
there and remains for about 30 seconds.

Now this hasn't a great impact with the test case because it, really, 
does not open a new window on the PC screen.

With Emacs (GTK build) the things are a little different.

When one opens a dialog, for example, to load a file to edit, the 
'gam_server' starts running; it remains running even after closing the 
dialog (and this seems to be expected).

However, when one decides to quit from Emacs, the 'emacs' process is 
removed, as shows 'ps', but the Emacs window remains on the screen until 
gam_server is gone, i.e. after about 30 second. This, at first sight, 
seems that Emacs is hanging.

Is this behavior to be expected? It looks strange to me... On GNU/Linux, 
with a similar GTK build of Emacs I do not see this behavior.


Cheers,
    Angelo.
