which uses icc as external preprocessor, and this doesn't work
because it assumes that // is a C++ comment and cuts whatever
follows. You should use the fortran preprocessor instead. The 
first lines of the make.sys file should look like (beware the tabs)

.SUFFIXES :
.SUFFIXES : .o .c .f .f90
.f90.o:
        $(MPIF90) $(F90FLAGS) -c $<
.f.o:
        $(F77) $(FFLAGS) -c $<
.c.o:
        $(CC) $(CFLAGS) -c $<

and the lines

> F90FLAGS       = $(FFLAGS) $(FDFLAGS) $(IFLAGS) $(MODFLAGS)
> F90FLAGS_NOOPT = $(FFLAGS_NOOPT) $(FDFLAGS) $(IFLAGS) $(MODFLAGS)

should be

> F90FLAGS       = $(FFLAGS) -nomodule -fpp  $(FDFLAGS) $(IFLAGS) $(MODFLAGS)
> F90FLAGS_NOOPT = $(FFLAGS_NOOPT) -nomodule -fpp $(FDFLAGS) $(IFLAGS) 
$(MODFLAGS)
