+Subject: [PATCH] Trim last argument to gcc if empty, on Darwin
+
+On Darwin, the last argument to GCC is coming up as an empty string.
+This is breaking the build of proto_library targets. However, I was not
+able to reproduce with the example cpp project[0].
+
+This commit removes the last argument if it's an empty string. This is
+not a problem on Linux.
