"c:\cygwin" is mounted as "/". Your Windows drives (c:, d:) are mounted 
under /cygdrive (/cygdrive/c, /cygdrive/d).

This is correct behavior. Only programs compiled against cygwin1.dll are 
aware of Cygwin-style paths. vim is available for Cygwin, maybe gvim is as 
well (try http://cygwin.com/packages/ , try Google, try searching the 
mailing list).

The name of the directory is WINNT, not winnt. bash will tab-complete 
successfully if you give it the right name (exceptions include /dev).
