Re: Same test-path-utils behaves differently on different Windows systems

[Sebastian Schuberth <sschuberth@gmail.com>]

Hi again,

the problem can also be reproduced in an easier way, independently of
mingwGitDevEnv and using the mingw_path function instead of
relative_path. If I install msysGit 1.8.4 from [1] and run
test-path-utils I get this on Windows Server 2008 R2 64-bit:

$ test-path-utils mingw_path /a/b/
a:/b/

But if I install [1] on my local Windows 8 64-bit I get:

$ test-path-utils mingw_path /a/b/
C:/msysgit/msysGit/a/b/

So the only obvious thing that changed is the Windows version, but I
find it hard to believe that this influences MSYS path mangling.
