It is.  HOME=C:\

It is.  (But is that location really required, for Cygwin itself to work?)

Dunno how to check that.  In bash, cd $HOME and cd ~ take me to /cygdrive/c, if
that helps.

FWIW, I am using an old version of Cygwin, having heard of various problems that
some Emacs users with more recent versions.

No, I don't have any details about the reported problems or which versions of
Cygwin.  Just take it as given that I'm not about to change Cygwin versions
anytime soon.  If there is no problem here with a more recent Cygwin build, then
that's good news and we can close this bug.

FWIW - My Cygwin version dates from 2006.  I don't see any README file or doc
and I cannot find how to determine the version #.  No, I didn't try googling
etc.

HTH.
