-	* Added board support fot the ZiLog ez80Acclaim! ez80f910200zco Development Kit.
-	* Fixed several compilation errors in fixed precision math library when built
-	  against toolchains that do not support 64-bit type 'long long'.
-	* Fix errors in some function prototypes in dirent.h
-	* Add eZ80F91 EMAC driver
-	* Fix recvfrom() compilation error -- only noted under ZDS
-	* Updated all ARM Make.def files to work with gcc 2.4.2 (However, there are
-	  still some build issues associated with that toolchain in use of arm-elf-objcopy
-	  -- see the TODO.txt list for details)
-	* Fix problems with Z16F and eZ80 compilation introduced with recent changes.
