+*******************This section is added by Heromyth*****************************
+Updated on 2007-7-21, by Heromyth <[email protected]>
+
+
+Notice:
+	1) The generated DLLs are *not* compatible with the ones built
+with the other compilers like VC8, especially for GLUT. 
+
+	2) Although more tests are needed, it can be used individually!
+
+	3) You can set the options about whether using STDCALL to build MESA. The 
+config file is <Mesa3D-root>\configs\config.mgw. The default setting is that:
+		ALL_USING_STDCALL = 1
+, which means using STDCALL to build MESA. 
+
+	4) Of course, you can MESA without using STDCALL,I like this:) 
+The setting is :
+		ALL_USING_STDCALL = 0
+To do this, however, you must modify wingdi.h which is in MingW's include dir. 
+For example, run:
+	notepad	C:\MingW\include\wingdi.h
+, and delete all the lines where all the wgl*() functions are. Because they would 
+be conflicted with the ones in <Mesa3D-root>\include\GL\mesa_wgl.h.
