Summary: In winuser.h BLENDFUNCTION not found.

Initial Comment:
I am using MinGW-3.1.0-1 which has gcc 3.2.3.

Trying to compile CPPUNIT I got an error message saying
that BLENDFUNCTION is undefined. I have investigated
the problem, and I found the error to be in the win32
heater files, and I also found the following solution
to the problem.

In the file winuser.h the function mentioned below must
 be encapsulated in the precompiler directive if as
shown below. Other ways the BLENDFUNCTION structure
will appear as undefined in the winuser.h file. 

#if !(defined NOGDI || defined  _WINGDI_H)
BOOL WINAPI
UpdateLayeredWindow(HWND,HDC,POINT*,SIZE*,HDC,POINT*,COLORREF,BLENDFUNCTION*,DWORD);
#endif

The structure BLENDFUNCTION  is declared in the
wingdi.h. When you write a win32 program you include
the windows.h file which includes both wingdi.h and
winuser.h, with wingdi.h being include firs. However
wingdi.h is only included in windows.h if "#if
!(defined NOGDI || defined  _WINGDI_H)" is true, and
hence the same precompiler directive is needed for the
UpdateLayeredWindow() function form winuser.h.

This seems to have been fixed in current CVS sources. Please
reopen if that's not the case.

The problem you report has caused modification in some fashion in the official CVS for the given package.  The w32api and 
mingw-runtime official CVS reside in the winsup CVS directory tree for Cygwin.  Those package CVS trees are periodically 
merged into the MinGW CVS tree.  If you still find problems then please open a new report.
