I suggest to modify the compiler options in pypy.translator.platform,
on windows first.

- use the /STACK linker option to reserve a stack large enough for
pypy (this affects only .exe, not dlls)
- set the MAX_STACK_SIZE preprocessor symbol used in by
LL_stack_too_big() in src/stack.h,
to a value slightly lower than the one above.

For optimized build, stacksize=512Kb is enough (this is the default
value in src/stack.h)
For debug build stacksize=4Mb works on win32.

I don't know the gcc options very well.
What do you think of adding these two:
        "-DMAX_STACK_SIZE=%d" % (stacksize - 1024)
        "-Wl,--stack,%d" % stacksize
