- cc65 2.13. allows to define all necessary paths through the single env var CC65_HOME.

- cc65 2.13. allows to override the stacksize from the linker command line thus eliminating the need for linker configs maintained by Contiki.
- cc65 2.13. integrates the startup code with the library. In 2.12. the startup code pulled in main(). Now main() is supposed to pull in the startup code. But  if main() resides itself in a library (as with Contiki) then nothing is pulled in at all :-(. The workaround is to pull in main() explicitly through the new option -u (working like the same GCC option).
