mpicc -show

clang -Wl,-commons,use_dylibs
-I/opt/moose/mpich/mpich-3.2/clang-opt/include
-L/opt/moose/mpich/mpich-3.2/clang-opt/lib -lmpi -lpmpi

mpicc for MPICH version 3.2
clang version 3.9.0 (tags/RELEASE_390/final)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /opt/moose/llvm-3.9.0/bin
clang-3.9: warning: argument unused during compilation: '-I
/opt/moose/mpich/mpich-3.2/clang-opt/include'


I guess because we are using a customize installation of clang.
