[svn-r13894] Description:
On Windows, Mingw interprets all parameters starting with '/' as paths, and replaces the '/' with its home directory, "C:\Windows\msys\".  This was a problem in h5diff tests such as:
        h5diff h5diff_101.txt $FILE1 $FILE1 /g1/d1  g1/d2  -v

I've removed the leading '/', as h5diff will interpret it the same either way.

Tested:
kagiso, linew, and smirom, via h5committest
mingw on Windows XP
