if you want don't inlcude
so we must remove
adler32_combine64
crc32_combine64
gzoffset64
gzopen64                                 
gzseek64                                 
gztell64                                 

in both contrib\vstudio\vc9\zlibvc.def and contrib\vstudio\vc10\zlibvc.def

I believe that your changes are incomplete, since in order to use the
library, zlib.h or zconf.h needs to be modified to provide the off64_t data
type (as __int64).  In any case, I am reluctant to include the
_LARGEFILE64_SOURCE;off64_t=__int64;lseek64=_lseeki64 changes in this
version.  A great deal of thought went into the LFS (Large File Summit)
definition for Unix systems, in order to avoid binary compatibility issues.
I think it will take a little while to iron out those issues for zlib on
Windows, so I would like to defer the implementation of 64-bit support for
Windows to the next version.

Mark
