Cygwin was working fine. I rebooted. Cygwin broken.

Ok. This says:
# 1) From existing HOME in the Windows environment, translated to a
# 2) from /etc/passwd, if there is an entry with a non empty directory
# 3) from HOMEDRIVE/HOMEPATH
# 4) / (root)
I just brought up a cmd shell and entered "set" and looked at the result.
1. I don't have a "HOME" variable setting.
2. /etc/passwd doesn't exist in Cygwin.
3. I DO have both HOMEDRIVE and HOMEPATH set, and that points to my Windows
home directory, which DOES exist.
4. This is what I am getting.
So, before this reboot, my Cygwin home directory has always been
"/home/<myuid>", which has always resided at "c:\cygwin64\home\<myuid>".
After the reboot, my Cygwin home directory is "/", which appears to
translate to "c:\cygwin64" (from "cygpath -w /"). However, according to
the rules listed in /etc/profille, I SHOULD be getting home set to
"c:/Users/<myuid>", although I don't want that.
Any other ideas?
