Hello Csaba/John,

sorry for the late response but I always get interrupted in my projects...

After I followed the advice from John and disabled the compilation of the 
runtime libraries the make of poolalloc works now.
The only left messages in the Safecode project are now:

...

When I patch the function getProgramCounter to return 0 only 
(getProgramCounter (void * context){return 0;}) then I get the following 
stuff:

Why is it here a problem to remove a file that does not exist? And what is 
the issue with this MADV_FREE define?


> Just out of curiosity, why do you need SAFECode to work on Windows?
In my company the whole tools chain is built on windows and so also my 
solution has to be solved on it.
