"Hack-fix" some headers to remove the forward declaration of typedef struct _CONSOLE *PCONSOLE;, which makes GCC 4.4.3 angry, but makes GCC 4.7.2 stay imperturbable. svn path=/branches/ros-csrss/; revision=58725

* Screen buffer structure represents the win32 screen buffer object. *
|
|
* Internally, the portion of the buffer being shown CAN loop past the *
|
|
* bottom of the virtual buffer and wrap around to the top. Win32 does *
|
|
* not do this. I decided to do this because it eliminates the need to *
|
|
* do a massive memcpy() to scroll the contents of the buffer up to *
|
|
* scroll the screen on output, instead I just shift down the position *
|
|
* to be displayed, and let it wrap around to the top again. *
|
|
* The VirtualY member keeps track of the top Y coord that win32 *
|
|
* clients THINK is currently being displayed, because they think that *
|
|
* when the display reaches the bottom of the buffer and another line *
|
|
* being printed causes another line to scroll down, that the buffer IS *
|
|
* memcpy()'s up, and the bottom of the buffer is still displayed, but *
|
|
* internally, I just wrap back to the top of the buffer. *
