MSVC 2012 issue with %zu format specifier

[yangyanli]

This was reported in closed issue #146. However, this is issue is so annoying, so I am recreating this issue report.

Could someone confirm whether %lu works for other platforms?

%lu does well on both clang 3.5.0 and gcc 4.8.1 (x64).
Even without warnings (-Wall -Wextra -pedantic are on).

Hi @yangyanli, please provide a patch as a pull request. See here for more information: https://github.com/PointCloudLibrary/pcl/blob/master/CONTRIBUTING.md. Point is, that most devs use Linux, so this is not important for us. Also, this is a good way to get started developing for PCL ;).
