From 10183d907979904acb90f38e0a26fd72a074ba3e Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 31 Aug 2015 12:57:45 +0000 Subject: [PATCH] mingw: support UNC alternates Just like we support having alternates pointing to different drives, we want to support alternates pointing to network shares, i.e. UNC paths. Technically, what we do in this patch is not to support UNC alternates, but to support UNC paths when normalizing paths. But the latter implies the former, and the former really was the motivation for this patch.
