Re: cygwin 1.3.21 breaks ssh terminal interaction

[Ronald Landheer-Cieslak <ronald at landheer dot com>]

try using an AllocConsole() in your non-Cygwin app and in your Cygwin app, 
like so:

#include <windows.h>
#include <io.h>
#include <stdio.h>
#include <fcntl.h>

// STC for the phantom console 1.3.21-1 problem
inline void OpenConsole(void)
{
   int hCrt;
   FILE * hf;

   if (AllocConsole())
   {
      #ifndef __CYGWIN__
      hCrt = _open_osfhandle((long)GetStdHandle(STD_ERROR_HANDLE), 
_O_TEXT);
      hf = _fdopen( hCrt, "w" );
      #else
      hf = fdopen( 2, "w" );
      #endif
      *stderr = *hf;
      setvbuf( stderr, NULL, _IONBF, 0 );
      #ifndef __CYGWIN__
      hCrt = _open_osfhandle((long)GetStdHandle(STD_OUTPUT_HANDLE), 
_O_TEXT);
      hf = _fdopen( hCrt, "w" );
      #else
      hf = fdopen( 1, "w" );
      #endif
      *stdout = *hf;
      setvbuf( stdout, NULL, _IONBF, 0 );
   }
}

int main(void)
{
	OpenConsole();
	
	printf("Hello, world!\n");
	
	return(0);
}

Compile this with -mno-cygwin and without it, and run it from cmd. The 
Cygwin app will allocate a new console, the native app won't.

Is that the STC you were looking for (or is it not the right problem)?
