Description of problem:

I see this when I try to build dbus 1.1.4 with jhbuild one rawhide:

 gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I.. -fPIC -DDBUS_COMPILATION
-DDBUS_MACHINE_UUID_FILE=\"/opt/gnome2/var/lib/dbus/machine-id\"
-DDBUS_SYSTEM_CONFIG_FILE=\"/opt/gnome2/etc/dbus-1/system.conf\"
-DDBUS_SESSION_CONFIG_FILE=\"/opt/gnome2/etc/dbus-1/session.conf\" -g -O0
-D_FORTIFY_SOURCE=2 -g -O0 -march=core2 -Wall -Wchar-subscripts
-Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith
-Wcast-align -Wsign-compare -Wdeclaration-after-statement -fno-common -MT

This seems to be because of a missing #define _GNU_SOURCE in
dbus-sysdeps-unix.c. Maybe only within the #ifdef SO_PEERCRED there. Not sure
why this started breaking just now...
