[vtkusers] Problems with __int64 on cygwin.

[Dominik Szczerba]

Hi Sam,

This is something specific to MS Visual C++:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_langref___int8.2c_.__int16.2c_.__int32.2c_.__int64.asp

Add somewhere:

-D__int8=char -D__int16=short -D__int32=int "-D__int64=long long"
