+       * BaseTinyFirmware/GCC/avr463/Makefile: Added -Wl,-relax to linker\r
+       flags. On my system this crashes avr-ld.exe, but others have reported\r
+       a large reduction in firmware size with this option. I added this\r
+       option for others to try.\r

-       * added "volatile" to structure object and array declarations for objects\r

-       implicitly "guaranteed" accesses in (avr-)gcc but it should be a "better\r
-       safe than sorry" extension.\r
-       * enveloped access to timer-values in timer.c to make them "atomic" since\r
-       they are unsigned long\r
