bug report windows x64

In the latest 1_8_cmake branch, I have found that when opening a file, the stack is corrupted during a call to stat(file ...)

Running on windows x64, I found that if I make a small change in
H5FDmpio.c
at/near line 943 and add an #ifdef _WIN64 to use _stat64 instead of stat, then all is well and everything runs fine.

Attached is a patch, but I'm not sure if this is the correct fix (for all scenarios). I ran a dashboard test after making the change and submitted it to the experimental builds of today. Machine dino.cscs.ch

John,
  Instead of the #ifdef try changing "struct stat" to "h5_stat_t".
If the configuration process is correct, this may be all that is needed. The file later on uses the correct "HDstat" call which is an alias to the real function.
