Almost all of Fortran 77 is included in the later
standards F90, F95, and F2003, but there are a few
exceptions, for example non-integer loop variables.
The currently supported and developed Fortran
compilers implement Fortran 95. G77 is not being
maintained. Therefore I think that people programming
in Fortran 77 should use the subset (about 99%) of
the language that is present in F95. This can be
verified by compiling the code with g95 or gfortran
with the std=f95 option. F90 and F95 retain the fixed
source form of F77 as an option.

I think modifying code so that it is more robust and
readable constitutes real progress, especially for
people who will directly with the code.
