Building glib2 fails with

gsocket.c: In function 'g_socket_get_credentials':
gsocket.c:3548: error: storage size of 'cred' isn't known
gsocket.c:3550: error: 'LOCAL_PEEREID' undeclared (first use in this function)
gsocket.c:3550: error: (Each undeclared identifier is reported only once
gsocket.c:3550: error: for each function it appears in.)
gsocket.c:3548: warning: unused variable 'cred'
gmake[4]: *** [gsocket.lo] Error 1

This is due to patch-aq which adds socket credential support. However
netbsd-4 local sockets do not support LOCAL_PEEREID.

>How-To-Repeat:
Try to build glib2 on netbsd-4.
>Fix:
Make code conditional on existence of the LOCAL_PEEREID interface
or the specific NetBSD version that introduced it.
