This is petsc-3.7?

Looks like mpif.h is getting included in some module that your code
is currently using.

Is this module your code - or petsc code?

Is using mpi via module [perhaps mpi.mod is preferable over mpif.h] -
then you can do something like:

#define PETSC_AVOID_MPIF_H
#include <petsc/finclude/petsc.h90>
