  Nope.  This problem was reported in PR 4347 (where you'll find a fix) and
patched on the trunk shortly thereafter.  Along with the report was a request
to add -DNETGROUP to CFLAGS (now CPPFLAGS), which was also implemented on
the trunk.  Recently, the change to the Makefile was pulled up to the release
branch, activating the problem on that branch, but the fix to hosts_access.c
was not pulled up with it.  I hope someone will get to that sometime...
