error "SEEK_SET is #defined but must not be for the C++ binding of MPI

I am trying to compile RedMD application with intel parallel studio 2013,
and i am getting following error!

Making install in src

Though this error does not show up in cluster studio 2015 ,
Also a fix is available here (the reference link there is invalid that's why i am asking these questions! )but i want to know
Q1. why this error crops up with v2013
Q2. what is the role of -DMPICH_IGNORE_CXX_SEEK and -DMPICH_SKIP_MPICXX compiler flags?

Awaiting your reply!
