From 64b150213365db6be97a98d25884f87d83caacaf Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 8 Jan 2010 02:48:03 -0500 Subject: getline: split out for darwin systems At least on OS X 10.5 and older, getline does not exist. So split out the function from the mingw code so that we can pull it in for Darwin systems.
