Re-added jar to CVS as binary file (-kb).
Removed jar being checked into CVS as text file.
Replaced assumption on pointer width compatible unsigned integer with the X/Open System Interfaces Extension type uintptr_t.
- Adjust error messages to actually match error values.
Added cc65 Makefile.
Made actually use of the PACKED macro defined in types.h.
Allowed to map utils onto C-runtime functions by defining NVMUTIL_CRT.
Having disabled firmware upload for cc65 the uart interface is only used by system.in and system.out. So it is reasonable to implement it by mapping onto keyboard input / display output.
