Oddly enough, something like

filepath.Rel(`C:\tmp`, `C:\TMP`)

hangs on my Win7 box using tip. The problem doesn't happen with Go 1.5.1. Adding a couple of tests:

diff --git a/src/path/filepath/path_test.go b/src/path/filepath/path_test.go
index 057aa6a..3a11ec4 100644
--- a/src/path/filepath/path_test.go
+++ b/src/path/filepath/path_test.go
@@ -1034,6 +1034,8 @@ var winreltests = []RelTests{
        {`C:\`, `D:\`, `err`},
        {`C:`, `D:`, `err`},
        {`C:\Projects`, `c:\projects\src`, `src`},
+       {`C:\Projects`, `C:\projects`, `.`},
+       {`C:\Projects`, `c:\projects`, `.`},
 }

 func TestRel(t *testing.T) {

cause path tests to timeout after 6m0s when executing all.bat.
