Cygwin cannot use GetConsoleWindow because it doesn't exist before Windows
2000 (W2K).

GetConsoleWindow was added

2002-08-30  Christopher January <ccj00 AT doc DOT ic DOT ac DOT uk>

        * include/wincon.h: Define GetConsoleWindow(void).

I added the guard per MSDN documentation after complaint from Pierre.

2002-09-03  Earnie Boyd  <earnie AT users DOT sf DOT net>

        * include/wincon.h (GetConsoleWindow): Add _WIN32_WINNT >= 0x0500
guard.

We have WINVER set to 0x0400 to avoid the problems you mention.

is what is causing the problems.  The code needs conditionalized further,
because the function
doesn't exist pre W2K.  The ChangeLog also needs adjusted to mention the
autoload.cc changes.

Yes, Cygwin is what is broken with this patch.

Earnie.
