Compile failure when including <opencv/cv.h> after <X11/Xlib.h> (Patch #1562)

Description

("my") <X11/Xlib.h> (fedora 16) contains

1#define True 1
2#define False 0

OpenCV-2.3.1/modules/flann/include/opencv2/flann/dist.h has (inside namespace cvflann):

1class True
2{
3};
4
5class False
6{
7};

The Xlib.h #defines make compilation fail.
A simple workaround is:

1#include <X11/Xlib.h>
2#undef True
3#undef False
4#include <cv.h>

But perhaps the #undefs could be added inside flann/dist.h ?
