Hi, I merged the changes from Tobias too fast... Despite the efforts, the win32 VM produced from HEAD are currently not usable when compiled thru cygwin/mingw I don't get a better health thru MSVC

The last functional VM I get (both win32 squeak.cog.spur and win64 squeak.stack.spur) are from

https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/43dca8fe50b7cc70901...

This prevents me to focus on the VMaker LLP64 changes. Maybe we'll have to revert... Thoughts?

Nicolas

follow up: more than 20 commits after the merge, we did not yet recover win32 health. win32 squeak.stack.spur segfaults with no usefull clue

If I comment this call, (replace with consoleWindow = NULL;) then it fails few steps later. It's just a symptom that we have broken something in the setup I searched refs to alloca - like we return or pass a dangling pointer to the local stack - unsuccessfully... It might be worth to try again thru MSVC IDE (complementary warnings, stack integrity checks, ...)
