System Workbench for STM32

So while waiting for a reply to my question, I am experimenting a little. I put the path to the arm-none-eabi version of cc1 in my path so that it is found. (I still have no idea of why I shuld have to do this for a new installation, so my previous question still stands.) But while the compiler runs, I now get this failure:

#include /* standard types definitions */

Any suggestions on how to fix this? Adding the path to stdint.h doesn't help. I think that is because of the implied meaning of the ange brackets.
