This sounds it is as expected.  You copied only cygwin1.dll so the
shell you started had a cygwin1.dll in another directory so that / is
mapped to the parent directory containing the cygwin1.dll the shell is
using.  However, when you use the win32 command shell there is no
previous mapping of / to the parent directory containing cygwin1.dll
so / is mapped to c:/some/path and the function correctly reports
