Python was not installed with cygwin, but I just did that.  which/where
indicate python is now running from the cygwin tree.  (I checked that
after changing ~/.hgrc to use cygwin style paths and removing some
environment variables as described below.)  The error changed from No
module named HTMLParser to No such file or directory for defpath.py and
jcheck.py.  However, ls shows that those file are there.

I changed ~/.hgrc to the cygwin style paths but that didn't help.

I removed PYTHONHOME and PYTHONPATH from my system env vars (I've never
needed them in the path) but that didn't help.  (I also removed it from
my PATH.)

It's Win 7 so even an Admin doesn't really have admin privileges, but
typically when I start my cygwin sessions I don't run them as "as
administrator".  This has worked in the past.

Note that I was off doing JavaFX work for a while and when I came back
to work on 7udev I forgot about needing cygwin 1.7.0 for builds so I
installed 1.7.15 (latest) and other than build I had no problems.  In
order to get my build to work I renamed my old 1.7.0 cygwin tree to
cygwin and then the build worked, but now mercurial isn't work for me as
described in my posts of today.  Maybe I need to use cygwin 1.7.0 for
builds and 1.7.15 for everything else.
