Larry:

Thanks for taking the time to reply, and thanks for the (~/.bash_login) suggestion.

Below are two tests cases for "ssh localhost date". The Linux
test shows that ~/.bashrc is read. The Cygwin case shows none of
~/{.bash_profile,.bash_login,.profile,.bashrc} are read. Doesn't this
seem like a bug?

Tests today w/linux suggest, this bash man page snippet is important:

  Bash attempts to determine when it is being run  by  the  remote  shell
  daemon,  usually  rshd.  If bash determines it is being run by rshd, it
  reads and executes commands from ~/.bashrc, if that file exists and  is
  readable.
