We have a rather large suite of fortran (mostly f90 - some f77) code that we
would like to "port" to gnu fortan. It is today compiled on Sun f90 (derived
from Cray CF90). We do have some issues...
This might not be defined as a gfortran error - but we do not know (how to find
out)
Our current compiler allows redefinition of variables. gfortran seems not to.
Is there a switch in gfortran that may be used?
heres the details & example:
>gfortran -v
