It's also worth noting that the path returned is not incorrect for Cygwin.
It's the POSIX form of the path when the drive is unmounted in Cygwin.
Of course, this path is only recognized by Cygwin-enabled tools.  For
those times in your code when you need to convert between POSIX and 
Windows paths (and back), there are functions to do so:

cygwin_conv_to_win32_path(IN const char *posix_path, OUT char *win32_path);
cygwin_conv_to_posix_path(IN const char *win32_path, OUT char *posix_path);

The command line equivalent is 'cygpath'.

For those curious, all of this information is in the email list archives,
the Cygwin User's Guide, and/or the Cygwin API reference.
