I use cygwin-mount and don't see this problem.
Make sure HOME is set in the Windows environment before launching emacs
(e.g. HOME=C:\home\ajm), that Cygwin is installed correctly at
C:\cygwin, and that the Cygwin mount table is correct (in my case with
/home mounted at C:\home). Cygwin will translate HOME to a POSIX path
automatically, and grep will be happy.
