+here is what happens when i apply the patch
+-------------------------------------------
+
+It works ! at least for my hello world.
+
+But mcs.exe still segfault (elsewhere)
+      
+I get the message: Your mono runtime and corlib are out of sync.
+           
+FYI i still use the .dll from mono-0.11, but i use mono from the cvs
+2002-05-09.
+
+i grepped the output for important things.
+
+$ mint mcs.exe
