+Subject: [PATCH 1/4] orc: Implement a windows helper for getenv()
+
+On Windows, getenv() is deprecated and does not work in all cases. On
+the Universal Windows Platform (UWP) it always returns NULL. Add
+a wrapper orc_getenv() that calls GetEnvironmentVariable on Windows.
+
+Also change semantics to always make a copy before returning.
+
