Max, Corinna,

First, Max, I'm sorry for the misinformation.

Second, Corinna, thanks for the correction.

Does this imply that the CYGWIN variable is consulted upon every "exec" 
system call to decide whether the ensuing program executes with "ntsec" in 
effect? I assume the check would not occur during a "fork" call.

By the way, I can have both a "tty" and a non-"tty" shell running 
concurrently, so it must be a process-by-process (checked on fork) or a 
program-by-program (checked on exec) characteristic.

The CYGWIN environment variable page of the Cygwin User Guide 
(<http://www.cygwin.com/cygwin-ug-net/using-cygwinenv.html> does not 
mention when the CYGWIN variable is consulted for the setting of the 
various options. Nor, as far as I can tell, does the "ntsec" page 
(<http://www.cygwin.com/cygwin-ug-net/ntsec.html>).
