[Libguestfs] [PATCH] hivex: Add O_BINARY flag to open calls for platforms where this isn't the default (such as Win32)

Hi As my cross platform registry editor (FRED available from https://www.pinguin.lu (sorry for advertising but I couldn't resist ;-))) is evolving, I recently added write support to it. While under Linux everything worked nice, the Windblows build didn't. It seems that Windows opens files by default in text mode (O_TEXT) which is a problem. The attached patch adds the O_BINARY flag to all open calls which solves the issue and allows libhivex to alter hives in Windows. I don't think this will harm on any other platform, so no fancy ifdefs this time :) ok? cu -- Unix _IS_ user friendly - it's just selective about who its friends are!
