Problem starting ESS for S-Plus 6 on Windows XP

[Rich Heiberger]

You have two choices.  One is to set the SHELL environment
variable
(setenv "SHELL" "c:/cygwin/bin/bash.exe")
(setenv "COMSPEC" "c:/cygwin/bin/bash.exe")

COMPSPEC makes M-x shell use bash instead of the default MS-DOS prompt.

With this choice M-x S works.

The other choice is to continue to use the default MS-DOS as your shell.
With this choice use M-x S+6-msdos to start S.

ps. NTemacs 21.3 has been available for several weeks.
