Cannot change console mode when set CYGWIN=tty

[Mike Gingell <mgingell at accesswave dot ca>]

Hi all!

In order to fix a minor problem caused by ^C being intercepted by bash, I 
set CYGWIN=tty before launching bash.  This solves the problem of cmd 
asking the user to terminate the batch job.  This is great, however, it 
breaks some of my other existing code, specifically the ability to change 
the Console mode.  i.e.  with CYGWIN=tty:

   Error getting console mode (Error 6): The handle is invalid.
   exception....GetConsoleMode
   [436]:[darkfriend:/d/rfr/mtQACE]:

without CYGWIN=tty, all works fine.....

This is the code that I use:
     // Turn off the line input mode, and echo the input mode.
     if (! GetConsoleMode(hStdin, &fdwOldMode)) {
         printErr("Error getting console mode", GetLastError());
         throw runtime_error("GetConsoleMode");
         }
     fdwMode = fdwOldMode & ~(ENABLE_LINE_INPUT
                            | ENABLE_ECHO_INPUT
                            | ENABLE_PROCESSED_INPUT );
     if (! SetConsoleMode(hStdin, fdwMode)) {
         printErr("Error setting console mode", GetLastError());
         throw runtime_error("SetConsoleMode");
         }

Is there a work around for this?  If not, I will have to run without 
CYGWIN=tty until I get a chance to dig into the source and find out what 
CYGWIN=tty really does.
Cheers!
