Ah.. its better to remove this method. i just left it to call super.
Originally (w/o my change) you are unable to change target dir, and i
found this annoying.
And.. i don't know how other people build squeak in windows, but all
my tries to build it from freshly unpacked gnutools and vm sources
failed.
Only after i did some changes in make files i did manage to build
squeak from freshly generated source tree.
Btw, i can provide my makefiles if someone interested.
