Missing case-insensitivity for certain filenames for Windows 7 guests

[xbaldauf]

Use a Windows 7 64-bit guest on VirtualBox 4.1.2 on Linux 64-bit hosts. Mount a VirtualBox-Filesystem share. Open a "cmd" box and change the current directory into a directory in this share. Execute following script:

mkdir test
mkdir test\Client
mkdir test\Client\a
mkdir test\Client\a\b
dir test\client\a
dir test\Client\a

What is expected that "test\client\a" should be accessible. What is actually observed is that "test\client\a" is not accessible. However, "test\Client\a" is accessible.

Running apps which access VirtualBox-shares is therefore quite restricted.
