(I need this fixed before 2.3.3 since it is critical to
something at work. I therefore promise to do it myself.)

I tracked down a segfault on Windows (XP) in some
windows registry traversal code I wrote.  It uses
_winreg.c, the crash is in PyEnumValue. I I think the
cause is that the requested value was very large
(several 100 KB) and the code does an alloca() for that
much.  I'm guessing this overflows the stack. The code
needs to be rewritten to avoid alloca() I fear...

I've fixed this in 2.4 and 2.3. (I still need to do a test
with a truly large registry value, but the only machine
where I can reproduce this is not in my possession, so it
may take a while).
