Win32 doesn't know what a st_ino is.  It's in the structure for standard 
compliance reasons.  Using st_ino from stat isn't possible.  It works 
for Cygwin because they emulate the inode structure using some hashing 
magic.

Rework the section of the patch using methods similar to what are most 
likely already found in other parts of the GCC code.
