Still working on this part.

These should hopefully be fixed with the latest trunk, please check.

This is due to the same problem as the first error above, so not fixed
yet.

This should now be fixed, please check.

This got me puzzled: the definition of REPARSE_DATA_BUFFER is now
guarded by this:

 #ifndef MAXIMUM_REPARSE_DATA_BUFFER_SIZE

Are you saying that MAXIMUM_REPARSE_DATA_BUFFER_SIZE is defined in the
MinGW64 build, but REPARSE_DATA_BUFFER is not?  Which MinGW64 headers
define MAXIMUM_REPARSE_DATA_BUFFER_SIZE and REPARSE_DATA_BUFFER?

Thanks.
