commit 1604c0fe0e5ce74538555c19a307ad38d0fca358
Author: Nick Mathewson <nickm at torproject.org>
Date: Tue Jul 10 10:14:24 2018 -0400
Add the compatibility definition for getdelim.c from netbsd.
We shouldn't actually need this code nearly anywhere we build:
getdelim is POSIX, and mingw provides it.
