That's interesting.  I've often used AttachConsole and freopen myself 
but it never occurred to me to check whether the file descriptors were 
still 1 and 2.

So this probably means that my sample called 
"gtestutils.c.alternative-2.patch" is the safest one to choose, since it 
doesn't make any assumptions about the file descriptor values.  Also (in 
theory) it should only attempt to write to the console if stdout / 
stderr appears to be valid (hopefully Windows would set them to NULL if 
they weren't valid?).
