 Dear maintainer of boost-gil-numeric,

 the gil examples which come with the boost package failed to compile on my
 system. Problems are caused by 2 lines in file
 /opt/local/include/boost/gil/extension/numeric/sampler.hpp

 The functions iround() and ifloor() are defined to return
 point2<std::ptrdiff_t> which is a long int on my system. That causes
 problems with related template definitions.

 You might want to conference the prototye definitions to be found in
 file
 /opt/local/include/boost/gil/utilities.hpp

 I created a diff:[[BR]]
