[vtkusers] Can't compile 5.2.1, CVS. *fixed* Bug in Cmake scripts with 64bit systems

[Mathieu Malaterre]

Hi paul,

  Thanks for the bug report. I feel there is something else going on
wrong. Did you start from a empty binary tree ? Did you change the
compiler *after* the first cmake configure step ?
  The test for VTK_[IO]STREAM_SUPPORTS_LONG_LONG is so obviously
simple, that I do not see how in the world it would possibly fails.

  Could you please try to reproduce the issue in a fresh (empty)
binary directory. Simply configure VTK (no need to build). And grep
for the value of VTK_ISTREAM_SUPPORTS_LONG_LONG in the generated
CMakeCache.txt.

Thanks for your help
