* wide_path.h (class wide_path): New class to convert Windows path to WCHAR win32 path, including long path conversion if necessary. * cygcheck.cc: Use class wide_path throughout to call Win32 functions taking potentially long filenames. (display_error): Use snprintf rather than sprintf. (display_error_fmt): Ditto. (dump_sysinfo): Use FindFirstFileW/FindNextFileW. * cygpath.cc: Use class wide_path throughout to call Win32 functions taking potentially long filenames. (get_device_name): Raise buffer size to take long pathnames. (get_short_paths): Convert to using GetShortPathNameW. (get_short_name): Ditto. (get_long_path_name_w32impl): Convert to equivalent of GetLongPathNameW. (get_long_name): Convert to using GetLongPathNameW. (do_sysfolders): Raise buffer size for POSIX pathname to PATH_MAX. (do_pathconv): In case of POSIX->Win32 conversion, convert to wchar_t Win32 path name and drop long pathname prefix if possible. (main): Call setlocale to accommodate wide char/multibyte conversions.
