Upgrade from 2.60 to 3.20

a few words about my experiences with upgrading from FreeRTOS 2.60 to 3.20.
- I opened a new port for my ATMega128 as I did for 2.60
- as many API functions have changed their return type
I needed to change most names to start with an ‘x’,  hungaryan? notation is annoying at this point
- I added FreeRTOSConfig.h to my source
- as size_t was introduced to protable.h I had to add stddef.h to my code for successful compilation

At the moment I need the following includes:
#include <stddef.h>
/* Scheduler include files. */
#include "FreeRTOSConfig.h"
#include "projdefs.h"
#include "portable.h"
#include "task.h"
#include "queue.h" 
#include "semphr.h"

Ok, just to mention it.

BTW sourceforge search function sucks as I was not able to search for ‘size_t’ without getting all results for ‘size’!

V3 introduces the header file FreeRTOS.h.  Include this and you can remove the explicit inclusions of

#include <stddef.h>
#include "projdefs.h"
#include "FreeRTOSConfig.h"
#include "portable.h"

Which tidies it up a bit.

It was a design decission that the task, queue and semphr headers be explicitly included - if you don’t like this (everybody has their own preference) then you can include them in the FreeRTOSConfig.h file on an application by application basis.

Ah, FreeRTOS.h !
Yes that works.
Seems to be a good solution.
