RE: FORTRAN implementation in Lenny
Hello Raju.
<f95> is a link in "/etc/alternatives" to "/usr/bin/gfortran".
When typing "gfortran -v" the options are:
]$ gfortran -v
Using built-in specs.

AFAIK, the GNU fortran compiler goes with the name gfortran (not f95).
Please give the output of "gfortran -v" so that we will know the
exact options you are using.
