OK. If you remove _errno and use _h5errno instead then the only thing 
required should be

#ifndef WIN32
 #include <unistd.h>
#else
 #include <io.h>
 #define open  _open
 #define close _close
#endif

this goes back in the private declarations

static h5part_int64_t    _h5errno = H5PART_SUCCESS;

and then you just use _h5errno in place of the old _errno except the 
system errno which is ok to leave alone on windows.

by not using the varname _errno, all the issues go away.

I won't send a patch because I've already made some other changes which 
were supposed to be patch #2
