Subject: File::Stat#blksize for Win32

Hi all,

Can we add support for File::Stat#blksize for Win32? 
Below is a simple script that demonstrates how to get
it.

Note that, although GetDiskFreeSpace() isn't reliable
for getting disk sizes over 2 GB, it is still reliable
for getting block size.

The only modification you might need is to attempt to
get the root path of the file name, rather than
resorting to NULL.

Regards,

Dan

#include <windows.h>
#include <stdio.h>

int main(){
   DWORD dwSectorsPerCluster, dwBytesPerSector;
   DWORD dwNumberOfFreeClusters,
dwTotalNumberOfClusters;
   int rv, blksize;
   
   rv = GetDiskFreeSpace(
      NULL, // or determine root path dynamically
      &dwSectorsPerCluster,
      &dwBytesPerSector,
      &dwNumberOfFreeClusters,
      &dwTotalNumberOfClusters
   );

   if(0 == rv){
      // Raise an error?  Return nil?
   }

   blksize = dwBytesPerSector * dwSectorsPerCluster;
   printf("blksize: %i\n",blksize);
   return 0;
}
