Hi,

It seems that getcwd() of bash continues the following approach until it 
reaches /.

1) readdir() on the parent directory.
2) for each dirent returned by readdir(), find the entry that matches 
the current dirctory (by comparing inode or something).
3) set parent dir as current, and continue from 1).

When you call getcwd() not under / (that is, C:/cygwin64), say 
/c/foo/bar (here I assume C drive is mounted on /c), step 2) will fail 
when current is /c, since readdir() on / doesn't return c as a dirent.

In short, getcwd() of bash doesn't work as expected in this situation, 
and if Cygwin's getcwd() implementation complies requirement by bash, 
HAVE_GETCWD should be enabled.
As far as I can see, HAVE_GETCWD enabled bash.exe is working fine here.
