anyone else have a <sys/stat.h> that DOESN'T #include <sys/types.h> ?

Do you mean config.h not confdefs.h?

You might also try regenerating configure with autoconf.  Different 
versions of autoconf behave slightly differently on different platforms. 
  OpenSSH currently uses 2.52 with a couple of mods (which is somewhat 
old, but it works properly on most of the platforms we know about).

It's added by the part of configure generated by this fragment of 
configure.ac:

# Checks for header files.
AC_CHECK_HEADERS([...] sys/stat.h [...])

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
