The kerberos test suite passes for me on RHEL6 (kerberos 1.10.3),
but I observe some compiler warnings that need to be dealt with:

$ ./configure --with-gssapi ...
$ time make -j8 -s

All of PostgreSQL successfully made. Ready to install.

I'm not very sure why the integer/pointer confusion in pgstat_bestart
doesn't cause hard crashes when using gss auth --- or does
this suite not actually test that?
