[CM] starting up cm under Cygwin 5.1 fails (Cygwin 5.0 expected)

[Terrence Brannon]

Using this cmdline:

     ~/mydocs/Scheme/cm-2.4.1/bin/cm.sh -e xemacs

I get the following error in the *inferior-lisp* buffer:

[1]>
*** - The value of TOK must be one of DARWIN, LINUX, CYGWIN_NT-5.0, FREEBSD
The value is: CYGWIN_NT-5.1
*** - UNIX error 13 (EACCES): Permission denied
Break 1 [2]>

Typing backtrace here did not yield a stack backtrace:

Break 1 [2]> (backtrace)

** - Continuable Error
EVAL: undefined function BACKTRACE
If you continue (by typing 'continue'): Retry
The following restarts are also available:
STORE-VALUE    :R1      You may input a new value for (FDEFINITION 
'BACKTRACE).
USE-VALUE      :R2      You may input a value to be used instead of 
(FDEFINITION 'BACKTRACE).
