Comment 1 Jose M. daLuz 2008-06-08 20:24:18 UTC 
I got the same error building 0.1.9 on Gentoo, Gnome 2.22.2. This happened with gcc 4.3.0 but only after updating glibc to 2.8 (2.8_p20080602).
Comment 2 Abhishek Dasgupta 2008-07-25 14:38:02 UTC 
According to the corresponding entry in gentoo bugzilla
(http://bugs.gentoo.org/show_bug.cgi?id=225403), the problem
was fixed by appending -D_GNU_SOURCE to CFLAGS. A similar thing
is also reported in Arch: http://bugs.archlinux.org/task/10989 with
the same resolution.
Comment 3 Olav Vitters 2008-08-18 08:05:16 UTC 
Could someone who fully understands the issue provide a patch please? And I mean for e.g. configure.in, not configure. This so I can apply the patch and do a non-maintainer release.
Comment 4 Pascal Terjan 2008-08-18 08:15:53 UTC 
I see 2 possible patches :
1/ Add #define _GNU_SOURCE in libgamin/gam_api.c and server/gam_channel.c
2/ Remove #define _GNU_SOURCE from server/gam_dnotify.c and add AC_GNU_SOURCE to configure.in

I think the second one is better
Comment 5 Olav Vitters 2008-08-18 10:47:33 UTC 
Ok, please provide a patch for #2.
Comment 6 Pascal Terjan 2008-08-18 11:37:54 UTC 
Actually it had already been fixed in svn 3 months ago...

Comment 7 Olav Vitters 2008-08-18 12:11:53 UTC 
Ah, I saw that commit, but didn't know it would fix this bug. I'll try and do a release (want to get an ok from DV).
