Forwarding to gcc list since there seems to be a C related problem here as well. 
Example code below.

Danny,

I experimented with your simple Hello World in C running on Cygwin, writing to
CONOUT$.  It does not error out, but does nothing.

On the gfortran side it creates a file named CONOUT$.

I would like to intercept this file name on mingw and cygwin systems and attempt
to map it to stdio in the gfortran runtime library. (band aid fix)

A couple of questions:

1) Is there a #define somewhere that I can use to conditionally compile this
"band aid" just for mingw and cygwin?  I have looked in config.h and did not
find anything useful.

2) At least on cygwin, since the example does not work for the C version (I have
not tried mingw, but presume it works there) is there a "system" level fix for
this problem that would be more appropriate?

Best regards,

Jerry

Examples:

$ cat test.c
#include <fcntl.h>
#include <sys/stat.h>
#include <stdlib.h>

int main()
{
 int fd= _open ("CONOUT$", _O_RDWR);
  if (fd >= 0)
   _write (fd, "Hello world", sizeof ("Hello world"));
 return 0;
}

$ cat test.f
       open(unit=29,file="CONOUT$")
       write(29,100)
100    format('Hello, world!')
       end
