Thanks Constantinos,
I tried the second option but i got the same problems.
I must not be using the flag properly i am sure.
Here is my opt file:


FC=mpif77
CC=mpicc
DEFINES='-D_BYTESWAPIO -DWORDLENGTH=4'
CPP='cpp  -traditional -KPIC'
NOOPTFLAGS='-O0'
#MAKEDEPEND=/usr/X11R6/bin/gccmakedep
#MAKEDEPEND=/usr/X11R6/bin/makedepend
LIBS='-L/usr/lib -lnetcdf'
INCLUDES='-I/usr/lib/mpich/include'


#  For IEEE, use the "-ffloat-store" option
if test "x$IEEE" = x ; then
     FFLAGS='-Wimplicit -Wunused -Wuninitialized'
     FOPTIM='-O3 -funroll-loops'
else
     FFLAGS='-Wimplicit -Wunused -ffloat-store'
     FOPTIM='-O0 '
fi


Thanks. n
