+       * BaseTinyFirmware/IAR: Port Martin's changes from 2008-04-03\r
+       to IAR\r
+       \r
+2008-04-03 Martin Thomas <mthomas@rhrk.uni-kl.de>\r
+       * BaseMegaFirmware/GCC: Experimental Master Code for the ATmega644\r
+       with basic "drivers" for\r
+               - keys incl. power-off with debounceing\r
+               - 74HC595 low-level "software-SPI"\r
+               - LEDs though 74HC595\r
+               - Power-off and Slave-Reset control though 74HC595\r
+               - hardware SPI for comm. with slave\r
+               - simple test-function for communication with slave\r
+       * BaseTinyFirmware/GCC/statefunc.c: \r
+               - prevent unneeded writes to eeprom if init fails\r
+               - prevent slave from entering sleep-mode standby if\r
+               "MASTER_INT" is low (so SPI communication with master is\r
+               possible even during the "8-second watchdog delay")\r
+\r
+2008-03-30 Kevin Rosenberg <kevin@rosenberg.net>\r
+       * BaseTinyFirmware/GCC Makefile's improved with more listing\r
+       output as well as added -Wl,-gc-sections option which stops\r
+       crashes using linker relaxation [thanks to Eric Weddington]\r
+\r
+2008-03-28 Kevin Rosenberg <kevin@rosenberg.net>\r
+       * BaseTinyFirmware/GCC/avr463/Makefile: Added -Wl,-relax to linker\r
+       flags. On my system this crashes avr-ld.exe, but others have\r
+       reported a large reduction in firmware size with this option. I\r
+       added this option for others to try.  *\r
+       BaseTinyFirmware/GCC/avr458/Makefile: Added missing file\r
+       \r
+2008-03-14 Martin Thomas <mthomas@rhrk.uni-kl.de>\r
+       Improvements to BaseTinyFirmware:\r
+       * added "volatile" to structure object and array declarations for\r
+       objects sed in main-thread and ISRs. I'm not sure about the\r
+       current state of implicitly "guaranteed" accesses in (avr-)gcc but\r
+       it should be a "better safe than sorry" extension.\r
+       * enveloped access to timer-values in timer.c to make them\r
+       "atomic" since they are unsigned long\r
+       * "atomic" access to singned int and unsigned int members of ADCS\r
+       * it maybe better to have one place to globally enable\r
+       interrupts ("sei").  Done in "initialize" now and not several\r
+       times in the driver init-functions.\r
+       * changed some space to tab as in the original code\r
+       * added header files to the AVR-Studio project workspace\r
+       * added -lm to the linker-options in the AVR Studio gcc-plugin,\r
+       not important for the basic application but might be good if\r
+       someone uses the ode as a base for own developments\r
+\r
+2008-03-12 Kevin Rosenberg <kevin@rosenberg.net>\r
+       * Initial GCC port performed and compiles without error\r
+       * Warning: Not yet tested on BC100 hardware!\r
