[Pkg-samba-maint] samba-4.16 progress so far

[Michael Tokarev]

Now I'm seeing a new issue.  A started from scratch
(after doing many trial-and-error things in my sbuild chroot), and am unable to
compile the thing at all.

It fails like this:

(with lots of other GSSAPI_FOO definitions which should be there
but for some reason they're not).

I've seen this before already, but it was, again, in somewhat unclean
build chroot, so I started from scratch and sbuild-apt update fixed it
(it worked one time at least, where I faced the smbconf link failures).
Now I can't make it to work without digging deeper.

Anyone know where/how these symbols supposed to be defined?

Thanks,
