+    Import Definition Files:
+    ------------------------
+    To link with Windows system DLLs, TinyCC uses import definition

-    The included 'tiny_impdef' program may be used to make .def files

-
-        tcc -run tiny_impdef.c opengl32.dll
+    To use it, put the opengl32.def file into the tcc/lib directory,
+    and specify -lopengl32 at the tcc commandline.
