I replaced the $realpath_root var with a literal path string, and 
everything works again as expected.

Dropping back to 1.15 branch, all's working again -- with the var.

Rebuilding PHP had no effect, neither did dropping back to earlier PHP 

Finally, I trashed all of nginx, and did a clean checkout/build.

And it works.  Of course.

No concrete idea what specifically was the problem ... but gone now.
