I actually hadn't run into these before.  I have recently changed my 
build setup so maybe that is what caused me to start seeing these.

I see glibc/conform/Makefile has some XFAILS:

# Pre-standard C feature no longer supported by GCC (obsoleted in
# newer POSIX standards).
test-xfail-XPG4/varargs.h/conform = yes
test-xfail-XPG42/varargs.h/conform = yes
test-xfail-UNIX98/varargs.h/conform = yes

# Header not provided by glibc.
test-xfail-XPG42/ndbm.h/conform = yes
test-xfail-UNIX98/ndbm.h/conform = yes
test-xfail-XOPEN2K/ndbm.h/conform = yes
test-xfail-XOPEN2K8/ndbm.h/conform = yes


The failures I am seeing are:

FAIL: conform/POSIX2008/arpa/inet.h/conform
FAIL: conform/POSIX2008/netdb.h/conform
FAIL: conform/POSIX2008/netinet/in.h/conform
