corrections to the Windows support to reconcile differences between Visual Studio and Cygwin. Includes parts of revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886. Of particular note, r886 overhauled the UTF-8/Unicode conversions to work correctly regardless of whether the local system uses 16-bit or 32-bit wchar_t. (I assume that systems with 16-bit wchar_t use UTF-16 and those with 32-bit wchar_t use UCS-4.) This revision also added a preference for wcrtomb() (which is thread-safe) on platforms that support it.
