I just updated gcc from 3.4.4-r1 to 3.4.5, and afterwards did an emerge -e system/world. During the latter, gnome-applets-2.12.2 failed to build with the following error: gweather-applet.c: In function `update_finish': gweather-applet.c:428: error: syntax error before '*' token gweather-applet.c:429: error: `NotifyHints' undeclared (first use in this function) gweather-applet.c:429: error: (Each undeclared identifier is reported only once gweather-applet.c:429: error: for each function it appears in.) gweather-applet.c:429: error: `hints' undeclared (first use in this function) gweather-applet.c:484: error: `icon' undeclared (first use in this function) make[3]: *** [gweather-applet.o] Error 1 make[3]: Leaving directory `/var/tmp/portage/gnome-applets-2.12.2/work/gnome-applets-2.12.2/gweather' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/var/tmp/portage/gnome-applets-2.12.2/work/gnome-applets-2.12.2/gweather' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/gnome-applets-2.12.2/work/gnome-applets-2.12.2' make: *** [all] Error 2 !!!

*** Bug 117393 has been marked as a duplicate of this bug. ***
Just FYI (I know you don't support it), I emerged Gnome 2.13 from Break My Gentoo, and gnome-applets-2.13.1 has the same error (starting at line 410). I'll look upstream for this error as well.
Okay, this is related to libnotify. The lines with errors are surrounded by #ifdef HAVE_LIBNOTIFY/#endif. I had libnotify-0.3.0 from Gentopia installed, and unmerging it gets rid of this error. This would still indicate a problem with libnotify support in gnome-applets, but perhaps this would be better addressed upstream.
Built fine with me with libnotify. However, libnotify isn't in portage, so it's not a gentoo bug.
