+*******************This section is added by Heromyth*****************************
+Updated on 2007-7-21, by Heromyth <zxpmyth@yahoo.com.cn>
+
+
+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.

+# updated : by Heromyth, on 2007-7-21
+# Email : zxpmyth@yahoo.com.cn
+# Bugs : 1) All the default settings work fine. But the setting X86=1 can't work.
+# The others havn't been tested yet.
+# 2) The generated DLLs are *not* compatible with the ones built
+# with the other compilers like VC8, especially for GLUT.
+# 3) Although more tests are needed, it can be used individually!
