Exactly.  The "* Libc: (libc).                 C Library" entry is
from GNU Libc, while the Cygwin library has a different entry.

Does the Cygwin libc manual have an index?  Are there any error
messages from Emacs?

I think nothing's wrong with the manual.  I cannot get Emacs 21.4 to
DTRT with "C-h C-i" on my machine as well, although I _know_ the glibc
manual is installed and reachable.  So I think this is a bug in Emacs
21.x that is fixed in Emacs 22.
