According to the "Bash Startup Files" section of the bash info page, bash
looks for either [/etc/profile, ~/.bash_profile|~/.bash_login|~/.profile]
when it's a login shell, and a [~/.bashrc] if it's a non-login shell.
Also from there:

   So, typically, your `~/.bash_profile' contains the line
     `if [ -f ~/.bashrc ]; then . ~/.bashrc; fi'
   after (or before) any login-specific initializations.

Hope this helps.

See <http://cygwin.com/cygwin-ug-net/ntsec.html#NTSEC-SETUID> and
<http://cygwin.com/faq/faq.html#SEC43>.  In short, "su" is not supported
under Cygwin, and "login" won't work by default for any user other than
SYSTEM (aka LocalSystem).

The preferred method for switching users is by running "ssh
user AT localhost" (after setting up sshd, obviously).  I'm guessing the
above FAQ entry should be updated as well.
