Re: Initialisation for the AT91... PIT if there is no kernel...

If i use only "Clean" and "Library F7" or only "Library F7" from the 
configtool, then changes in my CDL-seting's don't work the right way.
Thats because the "Clean" command don't delete the makefiles. And in the 
"\andrew1_build\hal\arm\at91\at91sam7s\current\makefile"  is written:

...
COMPILE := src/at91_misc.c src/timer_pit.c src/hal_diag.c
...

So i think this means, that the #ifdef's don't realy work, but that they 
don't allow the linker to link the wrong functions in the application.

An alternative would be:

#ifndef ...PIT...
 #error This file should not be compiled...
#endif
