Try with :

  ifc -I/opt/mpich-1.2.5/include -lmpi -w -o p_wg3 p_fdtd3dwg3_pml.f90

Btw, a cleaner way to compile mpi programs is to use the mpif90 
(mpif77 for fortran77) command (which is a wrapper for the real compiler). 
You should be able to make it use the ifc by setting the MPICH_F90 
(MPICH_F77 for fortran77) and MPICH_F90LINKER environment variables to 
choose which compiler to use, e.g. let's say you want to use the ifc 
compiler, and you're using bash, you would have to do:

  export MPICH_F90=ifc
  export MPICH_F90LINKER=ifc

and then, in order to compile your mpi program you should issue the 

  mpif90 -o p_wg3 p_fdtd3dwg3_pml.f90

Neither. Intel works fine with Oscar.
