+# Updated : by Heromyth, on 2007-7-21
+# 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!
