#11934: Various warnings in 1.60 MPL when compiling with nvcc
------------------------------------+-----------------------
 Reporter:  Alex Grund <a.grund@…>  |      Owner:  agurtovoy
     Type:  Bugs                    |     Status:  new
Milestone:  To Be Determined        |  Component:  mpl
  Version:  Boost 1.60.0            |   Severity:  Cosmetic
 Keywords:                          |
------------------------------------+-----------------------
 I'm compiling a larger project (
 https://github.com/ComputationalRadiationPhysics/picongpu/ current dev)
 which uses boost heavily. However a lot of warnings are issued. Since we
 are quite agnostic to warnings (compiling with many warnings enabled and
 -Werror) this is troubling and it would be great, if those are fixed in
 future versions. If I remember correctly older versions (1.58) did not had
 them.
