Correct the header comments in het.c and het.h (RM48/TMS570 demo) which were corrupt.
Correct version numbers in RX63N Renesas compiler demo.
Ensure stacks set up for tasks in the RX200 port layer end on 8 byte boundaries (was 4, which didn't matter but didn't match the definition).
Replaced unqualified (unsigned) in calls to standard functions with (size_t).
Each RTOS port has a demo application to demonstrate it's use.
+ The Demo/Common directory contains the demo application files as described on
the http://www.FreeRTOS.org WEB site. Each file creates one or more tasks.
The files in the Demo/Common directory are used by every demo application for
every port.
+ All the other directories contain a project or makefile for the demo
application targeted at a particular microcontroller.
For example, if you are interested in the ATMega323 demo application for
the WinAVR tools then the AVR_ATMega323_WinAVR directory contains the
relevant makefile. The makefile includes files from the Demo/ATMega323
and the Demo/Common directories. If this is the only port you are
interested in then all the other directories can be ignored.
