But look above: the DIR entry clearly shows it's the GNU Libc.  And
"C-h i" does work with it, as Pawel said.

Anyway, I don't understand how can the Cygwin version not work.  Emacs
doesn't assume anything about the libc manual, all it needs is the
index.  Are you saying that the Cygwin version of libc docs doesn't
have an index?  If so, it's not the GNU Libc manual.  (IIRC, Cygwin
uses newlib, not glibc.)

Again, read the original message above: Pawel says that he verified
that he did found the memset description via "C-h i".  So I think
there's nothing wrong with his manual.
