*******************************************************************************

 3. 6.97        - first internal release
		- V7.0

21. 6.97        - New library functions 'AllocVecPPC' and 'FreeVecPPC' for
		  memory allocation, including user-defined alignment.
		- V7.01

21. 7.97        - New 68K library functions 'AllocVec32' and 'FreeVec32'
		  allow to allocate memory which can be shared with PPC
		  tasks
		- New 68K library function 'SPrintF68K' allows to print out
		  debug information to serial/sushi.
		- V7.02

30. 7.97        - General adaption to the new ppc.library due to major
		  changes of ppc.library (i.e. dynamic binding).
		  The file dummy.elf has been replaced by a new one
		- Added private Cacheflush-routine to every internal
		  68K-Call because the automatic cache flushing of the
		  actual ppc.library (actually 44.17) doesn't work
		  anymore.
		- V7.03

 1. 8.97        - Changed the assembler macros RUNPOWERPC and RUNPOWERPC_XL
		  (powerpc.i) to support direct PPC-Library-Calls from 68K-
		  Functions. Note: the parameters 2-4 were shifted to the
		  right by one. New parameter 2: The Library-Offset (used
		  in the same way like in the macros RUN68K and RUN68K_XL).

11. 8.97        - Small bug fixed causing problems with debug output enabled.
		- V7.041
		- IMPORTANT! Special Note:
		  The powerpc.library V7 does NOT work with ppc.library 44.20.
		  Reason: The signaling-mechanism of the ppc.library is
		  definitively broken! Probably more reasons...

16. 9.97        - V7 works again (special hack implemented to bypass
		  ppc.library bugs).
		- Removed private Cacheflush (seems to be obsolete now).
		- V7.05

18. 9.97        - New library functions GetSysTimePPC, AddTimePPC, SubTimePPC
		  and CmpTimePPC for time measurement
		- New small demo program 'pixelOmania' to measure the
		  context switch performance (i.e. to compare V7 and V8+)
		- Reinstalled private Cacheflush (isn't obsolete at all...)
		- V7.06

29. 9.97        - New env variable 'earlyterm' implemented.
		  If the variable is not 0, then the mirror task of a 68k
		  task is removed at the last CloseLibrary of the 68k task,
		  instead at removal of the task.
		  Hope, this will fix the problems with WShell.
		- V7.07

 8.10.97        - RunPPC now interprets the PP_OFFSET field in the same way as
		  Run68K does. If PP_OFFSET is zero, than it works as before,
		  if it is not zero, a PPC library call is performed with the
		  base in PP_CODE and the library vector offset in PP_OFFSET.
		- V7.08

22.11.97        - Oh, DAMN. Exec tasks couldn't use RunPPC because of
		  DOS calls. These calls are now handled by a new
		  support process called 'Babylon5'.
		- V7.1

25. 3.98        - Stackswapping implemented to eliminate RAMLIB stack
		  problems
		  V7.2
