Newer glibc Version guards the definition of struct ucred (e.g. used in liblutil/getpeereid.c) by __USE_GNU, hence it is only available when _GNU_SOURCE is defined.

The matching glibc changelog only say "Cleanup namespace.". Here's the diff:

This is a bug in glibc. Luca Scamoni reported it upstream here http://sources.redhat.com/bugzilla/show_bug.cgi?id=6545
