I don't see anything wrong there. The value of
-X is well-defined if X is unsigned int; it's
equivalent to ~X + 1. Can you supply a test case
illustrating the actual bug?
Please bear in mind that the code is already
tested to LP64 hosts. Any bug related to this
particular code would also be a bug on LP64 hosts,
no? So, it's not likely that any bug here is specific
to Windows 64. If there is a bug, it should be
describable and fixable independently of Windows 64.
