+    Move objects before $LIBS to avoid link failures with --as-needed.
+    Do not override CFLAGS for video test.
+    Rearrange *FLAGS incl. some minor fixes.
+    Don't override VDRDIR, LIBDIR and TMPDIR in makefile.
+    Don't abuse LDFLAGS in makefile.
+    Define CC in makefile.
+    Include GL/gl.h for the GL_COLOR_BUFFER_BIT definition.
+    VideoInit() needs an argument.
