problems with git --git-dir on windows 7

Hello, We are using git on windows7(git-version 1.8.1; see below) and we get the following problem in using the command 'git --git-dir='

C:\UserTemp\git\appli3>git  --git-dir=C:\UserTemp\git\appli3 tag fatal: Not a git repository: 'C:\UserTemp\git\appli3'

but the repository is well defined,as we can run the following command:

C:\UserTemp\git\appli3>git log -1 --oneline 37cdbe0 Merge branch 'master' of L:/_ApplicationData/FBLU_IT-FLIT/se-DevelopSupp

When running the equivalent command on Linux, we don't have any problems: On Linux:

V1.0 V1.1 V2.0 V3.0

Could you help me please ?

Best regards

Manfred Schilz
